pg_controldata(1)

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 directory.  You can specify
       the data directory on the command line, or use the environment variable
       PGDATA.

ENVIRONMENT

       PGDATA Default data directory location
