In core code, inplace updates are specific to pg_class and pg_database. Adding PGXN modules, only the citus extension uses them on some other table.

Wrong datfrozenxid can cause premature clog truncation, which can cause "could not access status of transaction". While $SUBJECT could cause that, I think it would happen on both primary and standby. [1] seems to be about a standby lacking clog present on the primary, which is unrelated. > [0] > https://www.postgresql.org/message-id/flat/67EADE8F-AEA6-4B73-8E38-A69E5D48BAFE%40yandex-team.ru#1266dd8b898ba02686c2911e0a50ab47 > [1] > https://www.postgresql.org/message-id/flat/CAFj8pRBEFMxxFSCVOSi-4n0jHzSaxh6Ze_cZid5eG%3Dtsnn49-A%40mail.gmail.com
