That might make it even faster. But to be honest, I haven't tested that. Patrick Hi Patrick, you could also add the check for NOT(bar_semaphore.sem_emp) into the WHERE clause of the trigger.

Even if a trigger body with only "null;" in it will incur much more overhead than without the trigger at all.
