7       cluster
8

SYNOPSIS

10       pg_controldata [option] [[-D | --pgdata]datadir]
11

DESCRIPTION

13       pg_controldata prints information initialized during initdb, such as
14       the catalog version. It also shows information about write-ahead
15       logging and checkpoint processing. This information is cluster-wide,
16       and not specific to any one database.
17
18       This utility can only be run by the user who initialized the cluster
19       because it requires read access to the data directory. You can specify
20       the data directory on the command line, or use the environment variable
21       PGDATA. This utility supports the options -V and --version, which print
22       the pg_controldata version and exit. It also supports options -?  and
23       --help, which output the supported arguments.
