No, I think it's that you've got a plpgsql trigger function that
contains queries referring to credit_card_audit. Dropping and
recreating that table invalidates plpgsql's cached plans for those
queries.

We do have in mind to fix this (Neil Conway was poking at it, last
I heard) but it won't happen before 8.2 at the earliest. In the
meantime I'm wondering why you are insistent on dropping and recreating
credit_card_audit, as opposed to something less invasive like TRUNCATE.
