How do they compare to triggers dynamically EXECUTEing the inserts? Is that a better solution, or should one really just use the IF ... ELSIF ... ELSIF ... ELSE pattern as suggested in the new docs? (Which means one has to re-create the complete trigger each time a partition is added.) Best Regards Michael Paesold
