Add relallfrozen, an estimate of the number of pages marked all-frozen in the visibility map. pg_class already has relallvisible, an estimate of the number of pages in the relation marked all-visible in the visibility map. This is used primarily for planning. relallfrozen, together with relallvisible, is useful for estimating the outstanding number of all-visible but not all-frozen pages in the relation for the purposes of scheduling manual VACUUMs and tuning vacuum freeze parameters. A future commit will use relallfrozen to trigger more frequent vacuums on insert-focused workloads with significant volume of frozen data.
