Hi all,
As mentioned in [1], there is no regression tests for the SQL control
functions: pg_control_checkpoint, pg_control_recovery,
pg_control_system and pg_control_init.
It would be minimal to check their execution, as of a "SELECT FROM
func()", still some validation can be done on its output as long as
the test is portable enough (needs transparency for wal_level, commit
timestamps, etc.).
Attached is a proposal to provide some coverage. Some of the checks
could be just removed, like the ones for non-NULL fields, but I have
written out everything to show how much could be done.
Thoughts?
