The after trigger is probably the main source of the problem ---
have you any way of avoiding that?
(I wonder whether we can't improve on that, at least for the case of a
non-deferred after trigger, which'd have already been fired before we
exit the subtransaction. The trick is how to know that there's nothing
useful left in the subtransaction's per-transaction memory context ...)
