I had a need to read such things as the backend locale and the catalog
|
|
version number from the current database, and couldn't find any existing
|
|
program to do that.
|
|
|
|
The attached utility produces output like this:
|
|
|
|
$ pg_controldata
|
|
pg_control version number: 71
|

To access the pg_control file, the program must be run as the Postgres user,
|
|
and PGDATA must be set correctly in its environment.
