NAME
pg_controldata - display control information of a PostgreSQL database
cluster
SYNOPSIS
pg_controldata [option] [[-D | --pgdata]datadir]
DESCRIPTION
pg_controldata prints information initialized during initdb, such as
the catalog version. It also shows information about write-ahead
logging and checkpoint processing. This information is cluster-wide,
and not specific to any one database.
This utility can only be run by the user who initialized the cluster
because it requires read access to the data directory. You can specify
the data directory on the command line, or use the environment variable
PGDATA. This utility supports the options -V and --version, which print
the pg_controldata version and exit. It also supports options -? and
--help, which output the supported arguments.
ENVIRONMENT
PGDATA
Default data directory location
PG_COLOR
Specifies whether to use color in diagnostic messages. Possible
values are always, auto and never.
