<command>pg_controldata</command> prints information initialized during

<command>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 <envar>PGDATA</>.
