       pg_controldata - display control information of a PostgreSQL database


       pg_controldata [option] [[-D | --pgdata]datadir]


       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.


           Default data directory location

           Specifies whether to use color in diagnostic messages. Possible
           values are always, auto and never.
