Hi, I've defined a small trigger to increment a field each time the row is updated: > CREATE TRIGGER inc_trigger BEFORE UPDATE ON Table FOR EACH ROW EXECUTE PROCEDURE inc_function(); Works quite well, however the trigger is also fired if the table itself is modified. When deleting or inserting a single row, the trigger is executed for all rows contained in the table. Is this intetional, and if so, how can I get the behaviour to only execute the trigger when an update on the relation is performed?
