Yes, that makes sense.  One more point is that if the reason for v13 giving
better performance is extra blocks (which we believe in certain cases can
leak till the time Vacuum updates the FSM tree), do you think it makes
sense to once test by increasing lockWaiters * 20 limit to may
be lockWaiters * 25 or lockWaiters * 30.
