Install

To add the required PGDG / PIGSTY upstream repository, use:

pig repo add pgsql -u   # add PGDG + Pigsty repo and update cache (leave existing repos)

Install this extension with:

pig ext install zstd; # install by extension name, for the current active PG version
pig ext install pg_zstd; # install via package alias, for the active PG version
pig ext install zstd -v 18;   # install for PG 18
pig ext install zstd -v 17;   # install for PG 17
pig ext install zstd -v 16;   # install for PG 16
pig ext install zstd -v 15;   # install for PG 15
pig ext install zstd -v 14;   # install for PG 14
pig ext install zstd -v 13;   # install for PG 13

Create this extension with:

CREATE EXTENSION zstd;

Usage

Function	Return Type
`zstd_compress(data bytea [, dictionary bytea [, level integer ]])`	`bytea`
`zstd_decompress(data bytea [, dictionary bytea ])`	`bytea`
`zstd_length(data bytea)`	`integer`

zstd_compress compresses the provided data and returns a Zstandard frame. A preset dictionary may also be provided. The default compression level may also be overriden, valid values range from 1 (best speed) to 22 (best compression). The default level is 3.

If you want to override the compression level without using a dictionary, set dictionary to NULL.

zstd_decompress decompresses the provided Zstandard frame in data and returns the uncompressed data. A preset dictionary, matching the dictionary used to compress the data, may also be provided.

zstd_length returns the decompressed length of the provided Zstandard frame. If ZSTD_getFrameContentSize() is available it returns NULL if the length is unknown. If unavailable, it isn’t possible to distinguish the error, unknown decompressed length and zero decompressed length cases.

Example

Basic compress/decompress example:

CREATE EXTENSION zstd;

SELECT zstd_compress('hello world');
-- zstd_compress
-- --------------------------------------------
-- \x28b52ffd200b59000068656c6c6f20776f726c64

SELECT convert_from(zstd_decompress('\x28b52ffd200b59000068656c6c6f20776f726c64'), 'utf-8');
-- convert_from
-- --------------
--  hello world

Compress with level (1 for best speed, 22 for best compression, default to 3)

CREATE EXTENSION zstd;

SELECT zstd_compress('hello world',  NULL, 10);
-- zstd_compress
-- --------------------------------------------
-- \x28b52ffd200b59000068656c6c6f20776f726c64

SELECT convert_from(zstd_decompress('\x28b52ffd200b59000068656c6c6f20776f726c64'), 'utf-8');
-- convert_from
-- --------------
--  hello world
