An AFTER trigger is not fired until the interactive statement is about
to complete --- ie, after the SECURITY DEFINER function has returned.
There has been previous discussion (inconclusive) about changing the
time of invocation of AFTER triggers, but given the current timing this
is the behavior I'd expect.
