Cope with inplace update making catcache stale during TOAST fetch.
This extends ad98fb14226ae6456fbaed7990ee7591cbe5efd2 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).
