NAME
       pg_controldata - display control information of a PostgreSQL database cluster


SYNOPSIS
       pg_controldata [ 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  data-
       base.

       This  utility  can only be run by the user who initialized the cluster because it requires read access to the data direc-
       tory.  You can specify the data directory on the command line, or use the environment variable PGDATA.

ENVIRONMENT
       PGDATA Default data directory location
