14 pg_controldata prints information initialized during initdb, such as
15 the catalog version and server locale. It also shows information about
16 write-ahead logging and checkpoint processing. This information is
17 cluster-wide, and not specific to any one database.

19 This utility may 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
