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  and server locale.  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 may 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
