Well, there's going to be pain *somewhere* here, and we already know
that users will find the current 8.3 behavior unacceptable.  I'd rather
have autovacuum not make progress than have users turn it off because it
gets in their way too much.  Which I think is exactly what will happen
if we ship it with the current behavior.
