You have an 'after-update' trigger on a table that does an update on that same table, and you're wondering why that creates an infinite loop? You need to do this in a 'before-update' trigger and set NEW.timestamp, then return NEW. -- Mike Nolan ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
