Yup. It's a bit silly that we recognized the need to do that for oldestMultiXid yet not for oldestXid. BTW, is it really necessary for copy_xact_xlog_xid to invoke pg_resetwal so many times? Why can't we pass all of the update-this options in one call? Who's going to do the legwork on this? regards, tom lane
