MDEV-28769 earlier disabled the use if IDs with non-default collations in statements like: SET character_set_results=2/*latin2_czech_cs*/; SET character_set_client=2/*latin2_czech_cs*/; SET character_set_server=2/*latin2_czech_cs*/; SET character_set_connection=2/*latin2_czech_cs*/; MDEV-30824 later fixed "mysqlbinlog" to dump character set names instead of IDs in these statements: < SET @@session.character_set_client=33, ... /*!*/; > SET @@session.character_set_client=utf8mb3, ... /*!*/; However, mysqlbinlog from old (pre MDEV-30824) distributions can still produce incorrect statements with numeric non-default collation IDs. New servers should still be able to load old dumps. Allowing the use of "SET @@character_set_xxx=ID" with numeric non-default collation IDs but only if: - the current THD is a true slave thread or - the current THD a pseudo slave thread (loading a mysqlbinlog output).
