Samuel Gilbert <samuel.gilbert@xxxxxxxx> writes: > Here is a complete example demonstrating the issue I am encountering : What seems to be happening is: 1. The parent table has a NOT NULL constraint on modificationDate. 2. parent_dispatcher_trigger does RETURN NEW, so the tuple will be inserted into the parent table as well as the selected child (presumably this is not what you wanted ...) 3. There is no trigger that will replace the modificationDate for an insertion into the parent. So the parent insertion fails, after all the triggers have run. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
