... now, thinking about how does pg_dump deal with this, I think this
thread is all wrong, or at least mostly wrong. We cannot have triggers
in partitions with different names from the triggers in the parents.
pg_dump would only dump the trigger in the parent and totally ignore the
ones in children if they have different names.
So we still need the recursion bits; but
1. if we detect that we're running in a trigger which has tgparentid
set, we have to raise an error,
2. if we are running on a trigger in a partitioned table, then ONLY must
not be specified.
