Thanks for creating the patch! I feel the existing function here should be the wrapper of Ex function, so attached patch did not match the expectation. table_open() and table_close() are called both in UpdateSubscriptionRelState() and UpdateSubscriptionRelStateEx(). Another issue is that the variable "tag" is used by SET_LOCKTAG_OBJECT() even without the debug build. How do you feel the .diff file can be applied atop PG17 patch? It is mainly same as v4 patch but has some assertion. Best regards, Hayato Kuroda FUJITSU LIMITED
