In postgresql, there are two parts to implementing a trigger; the trigger function and the actual trigger on the table that calls this function. Here is a good example: http://www.postgresql.org/docs/8.2/interactive/plpgsql-trigger.html#PLPGSQL-TRIGGER-AUDIT-EXAMPLE One other point to be aware of, Postgresql does not allow your to reference other databases in the DB-cluster directly. It is possible but you need to add a contrib module called dblink: http://pgfoundry.org/projects/snapshot/ Hope this helps, Regards, Richard Broersma Jr. ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
