Обсуждение: pgsql: Fix trigger drop procedure

Fix trigger drop procedure

After commit 123cc697a8eb, we remove redundant FK action triggers during
partition ATTACH by merely deleting the catalog tuple, but that's wrong:
it should use performDeletion() instead.  Repair, and make the comments
more explicit.

Per code review from Tom Lane.
