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.

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
