I think his basic complaint is that doing the full logging pushup for
even short-duration queries is too expensive, and that logging only the
duration and not the query text or parameters makes a significant speed
difference.  I'm not at all sure that I buy that, but if it's true then
subsequent filtering obviously doesn't help.
