Actually, shouldn't we be checking just "!OidIsValid(pg_trigger->tgparentid)"
here?  Surely the other two conditions should already not matter either
way if tgparentid is set.  I can't see us starting to clone
for-statement triggers, but I'm not sure I trust the internal marking to
remain one way or the other.
