Backpatch regression tests added by 2d689babe3cb

A new plpgsql test function was added in 14 and up to cover for a bugfix
that was not backpatchable.  We can add it to older versions as a way to
cover other bits of DDL event triggers, with an exception clause to
avoid the problematic corner case.

Originally authored by Michaël Paquier.

Backpatch: 10 through 13.
