History

Noah Misch 536acda0bc 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.
