No, but it should be pretty trivial to write. Just set up a BEFORE UPDATE trigger that compares OLD.ts_field against NEW.ts_field and does a RAISE ERROR if they're different. The PL/pgSQL docs have a few decent examples of how to write a trigger function. -Doug ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
