Usage
pg_checksums: Activate/deactivate/verify checksums in offline Postgres clusters
pg_checksums_ext is a command-line tool (based on PostgreSQL’s built-in pg_checksums) that can verify, activate, or deactivate page-level checksums for a PostgreSQL cluster. It extends the built-in tool with online verification, SIGUSR1 progress toggling, fine-grained progress reporting, and I/O rate limiting.
Verify Checksums (can be done online)
pg_checksums_ext -D /path/to/data --checkEnable Checksums (requires clean shutdown)
pg_checksums_ext -D /path/to/data --enableDisable Checksums (requires clean shutdown)
pg_checksums_ext -D /path/to/data --disableAdditional Options
-D, --pgdata– data directory path--check/--enable/--disable– operation mode--progress– show progress reporting--filenode– check only a specific filenode--no-sync– skip fsync--verbose– verbose output--debug– debug output- Send
SIGUSR1to toggle progress reporting during operation
