pig v1.8.1

Thu, 03 Sep 2026 00:00:00 +0000

Pig v1.8.1 is a safety, correctness, and maintenance release on top of v1.8.0. It hardens command initialization, privileged log access, repository and build workflows, release integrity, and structured-output redaction. It also refreshes the embedded extension catalog and moves the build toolchain to Go 1.27.1 and cargo-pgrx 0.19.2. The embedded Pigsty version remains 4.5.0.

CLI safety and correctness

Read-only and configuration-independent commands no longer require a writable HOME or create ~/.pig as a side effect. Leaf commands preserve their declared initialization policy.
pig pg log, pig pt log, and pig pb log preserve arguments through sudo execution as the database OS user and reject unsafe log-file links.
pig do validates Pigsty names and rejects reserved Ansible cluster targets before execution.
Native PostgreSQL role detection is bound to the selected instance rather than an unrelated local default.
Structured results redact credentials, license material, and build-proxy identifiers while retaining truthful command failure.

Repository and build hardening

Repository add and remove operations now fail when any requested operation fails, deduplicate module selections, and preserve replacement boundaries.
Offline cache bundles reject unsafe paths, links, special files, and incomplete inputs; archive extraction remains rooted and fail-closed. The obsolete exported cache wrapper was removed after production moved to the structured result path.
Build source and artifact validation rejects incomplete or unsafe inputs. pig build proxy uses the package-provided service contract, treats its operands as optional, and keeps secret identifiers out of structured output.
Self-update verifies release checksums, and release tooling refuses dirty or mismatched-tag publication and immutable artifact replacement.

Toolchain and catalog

Go is updated to 1.27.1; Logrus to 1.10.2; GoReleaser to 2.18.0; and golangci-lint to 2.13.2.
pig build pgrx now installs cargo-pgrx 0.19.2 by default. Use -v when an extension requires an older pgrx line recorded in its catalog metadata.
The embedded catalog is refreshed from the maintained pgext view. It adds acdat 0.1.0, marks the superseded pgcontext_pgvector entry removed, and updates package versions, repository ownership, PostgreSQL coverage, and availability matrices.

Verification

The release is built from source commit e3d1eb4. The exact commit passed the full CI workflow, including randomized tests, command race regressions, vet, static analysis, dead-code detection, vulnerability scanning, and a GoReleaser snapshot. The tag then passed the Release workflow, which produced the published RPM, DEB, macOS, and Linux artifacts.

pig v1.8.0

Fri, 14 Aug 2026 00:00:00 +0000

Pig v1.8.0 makes Pigsty controller setup native. The two core setup commands, pig sty boot and pig sty conf, are now failure-aware Go workflows instead of wrappers around the legacy bootstrap and configure shell scripts. The release keeps the public catalog total at 575 packaged PostgreSQL extensions and embeds Pigsty 4.5.0.

Native `pig sty boot`

pig sty boot is now one native, failure-aware controller bootstrap transaction. It does not execute <PIGSTY_HOME>/bootstrap, and its HTTP download and archive extraction paths do not depend on curl, wget, tar, or gzip.

pig v1.7.0

Wed, 12 Aug 2026 00:00:00 +0000

Pig v1.7.0 is a repository compatibility and catalog release on top of v1.6.2. It makes China-mirror selection explicit, preserves native DNF module filtering by default, restores a streamlined EL7 repository catalog, and grows the bundled extension snapshot from 572 to 575. The embedded Pigsty version remains 4.5.0.

Highlights

-m|--mirror now selects the bundled china repository definitions directly. PGDG, Rocky Linux, Debian, Ubuntu, Docker, and other regional routes use the maintained mirror list instead of the former runtime PGDG proxy rewrite.
EL repository definitions no longer receive module_hotfixes=1 globally. Pigsty and PGDG repositories that intentionally override module streams opt in explicitly; BaseOS, AppStream, EPEL, and other repositories retain native DNF module filtering.
EL7 keeps a deliberately limited compatibility catalog: archived CentOS 7 Base/Updates/Extras/SCLo and EPEL definitions for x86_64, plus shared Pigsty and supported PGDG entries. The DNF-only module_hotfixes key is stripped when rendering EL7 YUM configuration.
Repository setup now reports unsupported platforms when the catalog has no matching definitions, instead of continuing with an empty repository set.
Release metadata is bumped to 1.7.0; the embedded Pigsty version remains 4.5.0.

Extension Catalog

Packaged extensions: 572 -> 575, with no removals.
3 new extensions: pg_local_cache 1.2.0, pg_statviz 0.1.0, and pg_policy 0.1.0.
Version refreshes include biscuit 3.0.0, pg_clickhouse 0.10.0, pg_search 0.25.2, pg_turbovec packages 1.29.0, pg_uuid_v8 1.1.0, and the Debian q3c 2.0.5 package.
Package metadata and availability matrices are refreshed. Run pig ext reload when you need a catalog newer than this release snapshot.

Compatibility Notes

No commands or global flags are removed in this release.
-m|--mirror is now an explicit China-region selection rather than a PGDG proxy rewrite. Use --region=default|china|europe when you need a specific route.
Custom EL repository definitions that require module-stream overrides must now set meta.module_hotfixes: 1 explicitly. This setting is intentionally omitted for ordinary OS repositories and removed on EL7.
EL7 is end-of-life and only has limited compatibility coverage; prefer EL8 or newer for current PostgreSQL and extension packages.

v1.7.0 · 2026-08-12

pig v1.6.2

Tue, 11 Aug 2026 00:00:00 +0000

Pig v1.6.2 is a feature and catalog release on top of v1.6.1. It grows the packaged extension catalog from 562 to 572, adds native Grafana dashboard schema v2 support, and improves local repository generation. The embedded Pigsty version remains locked at 4.5.0.

Highlights

pig sty grafana now accepts both legacy dashboard JSON and native dashboard.grafana.app/v2 Dashboard resources. Loading a v2 dashboard uses Grafana’s resource API so tabs and section variables survive the round trip; dumping preserves an existing v2 destination while new dumps keep the legacy format by default.
pig repo create now prefers sow create --pigsty --timeout 10m -- <dir> when SOW is available, requires the resulting repo_complete marker to exist as a regular file, and falls back to createrepo_c / dpkg-scanpackages on Linux.
Local repository creation now works on macOS through SOW, defaults to the current directory there, and does not require sudo. The Linux default remains /www/pigsty.
Release metadata is bumped to 1.6.2; the embedded Pigsty version stays at 4.5.0.

Extension Catalog

Packaged extensions: 562 -> 572, with no removals.
10 new extensions: pg_turbovec, pg_disorder, pg_mentat, plruby, jsonb_plruby, hstore_plruby, ltree_plruby, pg_describe, cat_tools, and pg_vault_tde.
12 version refreshes: timescaledb 2.29.1, q3c 2.0.5, pgmnemo 0.16.1, pg_search 0.25.1, citus 14.2.0, citus_columnar 14.2.0, provsql 1.12.0, plpgsql_check 2.10.4, pg_rational 0.0.3, pgbson 2.1.0, pg_readme 0.7.1, and pg_readme_test_extension 0.7.1.
Package metadata and availability matrices are refreshed. Run pig ext reload to replace the embedded release snapshot with the latest online catalog.

Compatibility Notes

No commands or global flags are removed in this release.
When SOW is installed, pig repo create now prefers it over the legacy Linux generators and checks that the completion marker exists before reporting success.
The catalog count is not a promise that every package is available on every PostgreSQL / OS / architecture combination; use pig ext avail NAME on the target host.
Package-manager and install-script upgrades use the newest version published by the configured Pigsty repository, which may lag GitHub. Use the GitHub assets when you need this exact release.

v1.6.2 · 2026-08-11

pig v1.6.1

Thu, 30 Jul 2026 00:00:00 +0000

pig v1.6.1 is a maintenance release on top of v1.6.0. It carries no new commands and no flag changes — the point of the release is the catalog that ships inside the binary.

What changed

Extension catalog refreshed. The embedded extension.csv is regenerated from the Pigsty package repositories, so pig ext list and pig install resolve against current package versions without a pig ext reload round trip.
Pigsty version aligned to 4.5.0. The embedded Pigsty version that pig sty and pig status report now points at Pigsty 4.5.0.
Version strings bumped across the build metadata and pig update.

The catalog embedded in the v1.6.1 release covers 562 packaged extensions across PostgreSQL 14–18 on EL 8/9/10, Debian 12/13, and Ubuntu 22/24/26, for both x86_64 and aarch64. Running pig ext reload can replace that release snapshot with a newer online catalog.

Getting Started

Mon, 01 Jan 0001 00:00:00 +0000

Here is a simple getting started tutorial to help you experience the core capabilities of the PIG package manager.

Short Version

curl -fsSL https://repo.pigsty.io/pig | bash   # Install PIG from Cloudflare
pig repo set                                   # One-time setup for Linux, Pigsty + PGDG repos (overwrites!)
pig install -v 18 -y pg18 pg_duckdb vector     # Install PG 18 kernel, pg_duckdb, pgvector extensions...

These commands install host packages. They do not run CREATE EXTENSION, change shared_preload_libraries, or restart PostgreSQL. After installation, run pig ext info pg_duckdb and pig ext info vector, apply the displayed preload/DDL steps to the intended database, and validate the service before production use.

pig v1.5.1

Wed, 08 Jul 2026 00:00:00 +0000

Pig v1.5.1 updates PG kernel forks to the latest package names.

Highlights

Add mirror/proxy mode to repo, build, sty, update, and extension update workflows; pig build rust -m also configures Cargo mirror settings with rsproxy.cn.
Add explicit PostgreSQL 19 beta build switches: pig build repo --beta, pig build tool --beta, and pig build pgrx -b, while keeping PostgreSQL 18 and PG14-18 as the stable defaults.
Refresh kernel and fork package aliases for IvorySQL, PolarDB, OrioleDB, OpenHaloDB, Babelfish, and the pgEdge suite.
Improve the Cloudberry package build flow for cloudberry, cloudberry-backup, and cloudberry-pxf.
Refresh source/package metadata for Cloudberry, Babelfish, OrioleDB, pgEdge, PolarDB, polarstore, zlog, libpgfeutils, and libfq.
Improve repository generation for newer EL release strings, including PGDG on EL9.6+ / EL10+ and EPEL’s EL10 10z stream.
Refresh extension versions including pg_ivm 1.15, spock 5.0.10, snowflake 2.5.0, pg_tde 2.2, decoderbufs 3.6.0, and IvorySQL 5.4 packages.

v1.4.0 · 2026-04-19

Catalog v2 Proposal: Immutable Typed Snapshots Instead of Bigger CSV

Thu, 13 Aug 2026 00:00:00 +0000

Decision date: 2026-08-13
Status: Pre-implementation proposal; security mechanism, overlay scope, packaging, and path ADRs remain open.
Current reference: pig ext and pig repo describe the v1 Catalog behavior.
Scope: A candidate PIG 2.0 publication and consumption model for product metadata, not Inventory or live system state.

Decision

Catalog v2 should be one immutable, verifiable snapshot composed of multiple typed targets. A manifest binds platform, repository, route, package-alias, extension, compatibility, Pigsty release, and public-key metadata to exact bytes. Candidate targets are validated together and activated through one pointer, preventing a new repository catalog from being mixed silently with an old extension matrix.

Bootstrapping a Pigsty Controller as a Recoverable Transaction

Fri, 14 Aug 2026 00:00:00 +0000

Decision date: 2026-08-14
Status: Implemented and released in pig v1.8.0.
Current reference: pig sty boot
Scope: Preparing a Pigsty controller and its package sources; not deploying a database cluster.

Decision

pig sty boot should be one native, failure-aware controller bootstrap workflow. It resolves an explicit source before privilege elevation, prepares online or offline repositories, installs only the required controller packages, proves Ansible is usable, and performs bounded finishing checks.

pig repo

Mon, 01 Jan 0001 00:00:00 +0000

The pig repo command is a comprehensive package repository manager. It can add, remove, create, and manage repositories on RPM systems (RHEL/CentOS/Rocky/Alma) and Debian systems (Debian/Ubuntu).

pig repo - Manage Linux APT/YUM Repo

  pig repo list                    # available repo list             (info)

Quick Start

# Method 1: replacement mode — use only when PIG should own the host's repo definitions
pig repo add all --remove --update    # remove old repos, add all required repos, update cache

# Method 1 variant: one step
pig repo set                          # = pig repo add all --remove --update

# Method 2: gentle mode - only add required repos and keep current repo configuration
pig repo add pgsql                    # add PGDG and Pigsty PGSQL repositories
pig repo add pigsty --region=china    # add Pigsty repositories with China region
pig repo add pgdg   --region=europe   # add PGDG repositories with Europe region
pig repo add infra  --region=default  # add INFRA repositories with default region
pig repo add all -m                   # explicitly select the bundled China-region mirrors

# If the commands above did not use -u|--update, run this as an extra step
pig repo update                       # update system package cache

Modules

In pig, APT/YUM repositories are organized as modules: groups of repositories serving a specific purpose.

pig v1.2.0

Mon, 23 Feb 2026 00:00:00 +0000

Extension catalog and alias resolution enhancements:
- Introduce dynamic PG category alias resolution by PG major version.
- Add OS-level alias overrides (ansible/bootstrap) and converge unknown distro fallback to PGDG-only.
- Add aliases such as node/infra and babelfish/cloudberry, and refresh extension metadata to reduce package resolution ambiguity.
Plan preview for high-risk operations:
- Add pig install --plan with structured execution plan output.
- Align preview semantics for pig pitr and pgBackRest repack/expire under --plan / --dry-run.
- Add plan-flag consistency tests to keep subcommand behavior aligned.
Native sty configuration capability:

pig v1.1.1

Sat, 14 Feb 2026 00:00:00 +0000

Fixes

Preserve symlink semantics during build-tree migration and support cross-device moves.
Handle a PostgreSQL log directory configured as the filesystem root without resolving files outside the intended directory.
Allow pig repo rm to remove repository modules whose names contain dots while retaining safe-path validation.
Accept safe relative symlinks when pig sty init extracts a Pigsty release archive.

SOW: Postpartum Care for 100,000 Packages

Tue, 11 Aug 2026 00:00:00 +0000

Today, let’s talk about Postpartum Care for Sows—a Chinese meme for the sort of absurdly specialized practical topic nobody expects to discuss. This time, the sow in question is my new open-source project, SOW.

When you maintain a PostgreSQL distribution, compiling the software is rarely the most painful part. The real pain is dealing with everything the build produces.

Pigsty maintains hundreds of components across multiple Linux distributions, CPU architectures, and major PostgreSQL versions. Multiply those combinations out, and the repository ends up with more than 100,000 artifacts: RPMs, DEBs, indexes, signatures, checksums, snapshots, and piles of metadata that exist only to keep package managers happy.

A Packaging Patch Has Been Corrupting Valkey's Memory Accounting Since 2017

Sun, 09 Aug 2026 00:00:00 +0000

I was updating the Redis module in Pigsty recently, adding Valkey as an alternative engine, and hit an upstream bug while packaging it.

If your Valkey runs on Debian or Ubuntu, and one day the disk fills up or the data directory permissions go wrong so snapshots stop saving — every failed save drops the instance’s memory counter a little. Once it goes below zero it wraps to 18446744073709518664. From then on, if you have maxmemory set, the server refuses every write until you restart it.

What Is a PostgreSQL Distribution?

Sat, 04 Jul 2026 00:00:00 +0000

People often ask me: what exactly is Pigsty?

My usual answer is: a PostgreSQL distribution.

The next question is usually: what, then, is a “PostgreSQL distribution”?

That is a good question. And the best place to begin is not databases, but operating systems.

I. Start with Linux Distributions

When most people hear “distribution,” they think of Linux distributions: Red Hat, Debian, Ubuntu, SUSE, Arch, and so on. But if Linux already exists, why do we need Linux distributions? What exactly is the relationship between the two?

The PostgreSQL Extension Encyclopedia: Bilingual and Ready to Use

Fri, 13 Mar 2026 00:00:00 +0000

Directory: Chinese · English

Extensions are the soul of PostgreSQL. Without them, PostgreSQL is just a very good relational database. With them, it becomes a platform that can swallow entire categories of database workloads.

The problem is that the extension ecosystem has long been awkward to use. People struggle to find extensions, understand them, and install them. You search GitHub for README files, check PGXN for packages, and then wrestle with OS and PG version compatibility by hand.

464 Extensions, Ready Out of the Box: The New PostgreSQL Extension Catalog

Sun, 08 Mar 2026 00:00:00 +0000

Today I put Claude Code to work on another genuinely useful project: a completely new PostgreSQL extension catalog. You can find it at pigsty.io/ext.

This is already the catalog’s fifth incarnation. After a long detour, it has returned to the Hugo + Docsy stack used by the first version and has been folded back into the main Pigsty website. That journey is a story in its own right, which I will save for later. First, let us look at what this version actually does.

Forging a China-Rooted, Global PostgreSQL Distro

Thu, 27 Nov 2025 00:00:00 +0000

Hi, I’m Feng Ruohang, author of Pigsty and an independent open-source contributor. Let’s talk about how to build a PostgreSQL distribution that is rooted in China and useful to the whole world.

The question isn’t whether PG will win—it already has. The question is: What role do we play in that victory? Spectator or protagonist? Follower or leader?

Why now

PostgreSQL is the default database

Stack Overflow’s 2025 survey shows 58.2% of professional developers use PG—18.6 points ahead of MySQL, and the gap is widening. New SaaS, AI startups, even OpenAI default to PG. DB-Engines rankings and JetBrains surveys tell the same story.

On Trusting Open-Source Supply Chains

Sat, 22 Nov 2025 00:00:00 +0000

Yesterday’s post “PG ‘Export Controls’ and Supply-Chain Trust” drew a comment from someone claiming to be an admin at a university mirror site (Tsinghua TUNA):

“As a university mirror admin, calling us ‘lying flat’ or ‘irresponsible’ is unfair and demoralizing.”

I replied:

Thanks for the feedback and for everything TUNA/university mirrors have done over the years. I see the PostgreSQL repo had synced again at the time—credit where it’s due.

PG Extension Cloud: Unlocking PostgreSQL’s Entire Ecosystem

Wed, 12 Nov 2025 00:00:00 +0000

WeChat link

PostgreSQL’s killer feature is extensibility. PostGIS, pgvector, pg_duckdb, pg_search—extensions turn PG into GIS engine, vector DB, analytics warehouse, search cluster. But compiling and shipping them reliably across distros is a nightmare, especially when official mirrors freeze or your network can’t reach upstream.

After two years of grinding, I’m launching PGEXT.CLOUD: the infrastructure for discovering, packaging, and installing PG extensions.

What’s inside

Extension catalog – Browse 431 extensions with metadata, docs, compatibility matrices, how-to guides. Think “Wikipedia for PG extensions.”
Binary repos – Native RPM/DEB packages for 14 Linux releases and 6 major PG versions. No Docker-only traps.
pig CLI – A 4 MB Go tool that wraps your existing package manager and hides the matrix of platforms/versions.

Try it on a fresh server/container:

Build and Packaging: An Overlooked but Scarce Skill

Mon, 18 Aug 2025 00:00:00 +0000

I was recently chatting with my friend Yurii, the founder of Omnigres. He wants to hire a PostgreSQL packaging expert and has even coined a title for the role: EEE, or Extension Ecosystem Engineer. It is an interesting idea. The job description is public, so I have included it at the end.

A Scarce Skill: Linux Packaging

I think this job description asks for a little too much: DevRel + SRE + DBA + build engineer + PostgreSQL specialist, all in one person. It almost reads as though it were written for me. But I have genuinely never met anyone else with that exact combination, so I advised Yurii that hiring a build engineer who knows Debian and Enterprise Linux packaging inside out would be more realistic. Even that will be difficult, though. Scarce hardly begins to describe people who understand build and packaging work. DevRel talent may be scarcer still.

The PostgreSQL 'Supply Cut' and Trust Issues in Software Supply Chain

Fri, 15 Aug 2025 00:00:00 +0000

This month saw a high-profile “open source supply cut” incident — KubeSphere deleting images and running away, but there’s another slightly more subtle “chokepoint case” I mentioned last month — “Chokepoint: PGDG Cuts Mirror Sync Channels”. This “PostgreSQL supply cut” played the role of litmus test, nicely revealing the true colors of various database and cloud vendors.

I’m deeply disappointed and have stopped treating domestic cloud vendors and university mirrors as upstream software supply chain sources, directly building my own up-to-date domestic mirror of PGDG YUM/APT repositories.

PGDG Cuts Off Mirror Sync Channel

Mon, 07 Jul 2025 00:00:00 +0000

Recently, while building Pigsty offline packages, I discovered that the PostgreSQL version installed during local testing wasn’t quite right - 17.4 was behind the latest 17.5 by one minor version. Also, when testing on EL10, I found several repositories were throwing errors. Strangely, using the global default repository in Hong Kong worked fine, but once using Chinese mirror sites locally, errors occurred.

Upon closer inspection, I found that domestic mirror sites had all lost synchronization with the PostgreSQL upstream repository: Tsinghua University Open-Source Software Mirror Site (TUNA) last successful sync was May 16th, while Alibaba-Cloud Mirror Site’s last sync timestamp was March 31, 2025. Foreign mirror sites like mirrors.xtom.de also had this problem, with last sync on June 20th, though you could clearly see signs of manual updates and disconnection from sync.

Postgres Extension Day - See You There!

Wed, 09 Apr 2025 00:00:00 +0000

The annual PostgreSQL developer conference will be held in Montreal in May. Like the first PG Con.Dev, there’s also an additional dedicated event - Postgres Extensions Day, focusing on all aspects of PG extension development, delivery, and release. The agenda has just been released with 14 sessions scheduled.

This time, I won’t just be an audience member - my talk is the first session of the afternoon: “The Missing Postgres Extension Repo and Package Manager”. I’ll introduce Pigsty’s extension repository and the pig package manager, sharing challenges and issues encountered when building and maintaining PG extensions, and sharing experiences, lessons, and insights from Chinese developers and database vendors (solo practitioners, haha) with global developers.

Pig, The Postgres Extension Wizard

Sun, 29 Dec 2024 00:00:00 +0000

Ever wished installing or upgrading PostgreSQL extensions didn’t feel like digging through outdated readmes, cryptic configure scripts, or random GitHub forks & patches? The painful truth is that Postgres’s richness of extension often comes at the cost of complicated setups—especially if you’re juggling multiple distros or CPU architectures.

Enter Pig, a Go-based package manager built to tame Postgres and its ecosystem of 440+ extensions in one fell swoop. TimescaleDB, Citus, PGVector, 20+ Rust extensions, plus every must-have piece to self-host Supabase — Pig’s unified CLI makes them all effortlessly accessible. It cuts out messy source builds and half-baked repos, offering version-aligned RPM/DEB packages that work seamlessly across Debian, Ubuntu, and RedHat flavors. No guesswork, no drama.

The Ideal Way to Deliver PostgreSQL Extensions

Sat, 02 Nov 2024 00:00:00 +0000

PostgreSQL Is Eating the Database World through the power of extensibility. When this post was first published, the repository packaged 390 PostgreSQL extensions as RPM / DEB packages for mainstream Linux distributions. The live Pigsty Extension Catalog has kept growing since then.

I believe the PostgreSQL community has reached a consensus on the importance of extensions. So the real question now becomes: “What should we do about it?”

What’s the primary problem with PostgreSQL extensions? In my opinion, it’s their accessibility. Extensions are useless if most users can’t easily install and enable them. But it’s not that easy.
