Noah Misch f9f47f0d93 Cope with inplace update making catcache stale during TOAST fetch. 
This extends ad98fb1422 to invals of
inplace updates.  Trouble requires an inplace update of a catalog having
a TOAST table, so only pg_database was at risk.  (The other catalog on
which core code performs inplace updates, pg_class, has no TOAST table.)
Trouble would require something like the inplace-inval.spec test.
Consider GRANT ... ON DATABASE fetching a stale row from cache and
discarding a datfrozenxid update that vac_truncate_clog() has already
relied upon.  Back-patch to v12 (all supported versions).
