Here's an updated patch with new GUCs that control how much each component
contributes to the autovacuum score for a table. They default to 1.0, but
can be set anywhere from 0.0 to 1.0 (inclusive). In theory, setting all of
them to 0.0 should restore the original pg_class order prioritization that
we have today. I haven't added corresponding reloptions for these GUCs, as
I'm not convinced we need them, but I can add them if folks think they
would be useful.
