Ah, right. I was thinking in terms of having TRUNCATE actually fire the existing ON DELETE-type triggers, but that's not really helpful --- you'd need a separate trigger-event type. So we could just say by fiat that an ON TRUNCATE trigger doesn't get any rowset information, even after we add that for the other types of statement-level triggers. Never mind ... regards, tom lane
