PG_CONTROLDATA(1) PostgreSQL Server ApplicationsPG_CONTROLDATA(1)NAME
pg_controldata - display server-wide control information
SYNOPSIS
pg_controldata [ datadir ]
DESCRIPTION
pg_controldata returns information initialized during
initdb, such as the catalog version and server locale. It
also shows information about write-ahead logging and
checkpoint processing. This information is server-wide,
and not specific to any one database.
This utility may only be run by the user who installed the
server because it requires read access to the datadir.
You can specify the data directory on the command line, or
use the environment variable PGDATA.
