pg_verify_checksums \u2014 verify data checksums in a PostgreSQL database cluster

\n
\n
\n

Synopsis

\n
\n

pg_verify_checksums [option...] [[ -D | --pgdata ] datadir]

\n
\n
\n
\n

Description

\n

pg_verify_checksums verifies data checksums in a PostgreSQL cluster. The server must be shut down cleanly before running pg_verify_checksums. The exit status is zero if there are no checksum errors, otherwise nonzero.

\n
\n
\n

Options

\n

The following command-line options are available:

\n
\n
\n
-D directory
--pgdata=directory
\n
\n

Specifies the directory where the database cluster is stored.

\n
\n
-v
--verbose
\n
\n

Enable verbose output. Lists all checked files.

\n
\n
-r relfilenode
\n
\n

Only validate checksums in the relation with specified relfilenode.

\n
\n
-V
--version
\n
\n

Print the pg_verify_checksums version and exit.

\n
\n
-?
--help
\n
\n

Show help about pg_verify_checksums command line arguments, and exit.

\n
\n
\n
\n
\n
\n

Environment

\n
\n
\n
PGDATA
\n
\n

Specifies the directory where the database cluster is stored; can be overridden using the -D option.
