SYNOPSIS

11       pg_controldata [ datadir ]
12

DESCRIPTION

14       pg_controldata prints information initialized during  initdb,  such  as
15       the  catalog version.  It also shows information about write-ahead log‐
16       ging and checkpoint processing. This information is  cluster-wide,  and
17       not specific to any one database.
18
19       This  utility  can  only be run by the user who initialized the cluster
20       because it requires read access to the data directory.  You can specify
21       the data directory on the command line, or use the environment variable
22       PGDATA.
