Noah Misch 5d94aa4dc3 In REASSIGN OWNED of a database, lock the tuple as mandated. ... Commit aac2c9b4fd mandated such locking and attempted to fulfill that mandate, but it missed REASSIGN OWNED. Hence, it remained possible to lose VACUUM's inplace update of datfrozenxid if a REASSIGN OWNED processed that database at the same time. This didn't affect the other inplace-updated catalog, pg_class. For pg_class, REASSIGN OWNED calls ATExecChangeOwner() instead of the generic AlterObjectOwner_internal(), and ATExecChangeOwner() fulfills the locking mandate. Like in GRANT, implement this by following the locking protocol for any catalog subject to the generic AlterObjectOwner_internal(). It would suffice to do this for IsInplaceUpdateOid() catalogs only. Back-patch to v13 (all supported versions). Kirill Reshke. Reported by Alexander Kukushkin.
