This doesn't surprise me too much, because sequences are not expected to contain any live XIDs, so the XID freezing mechanism ignores them. So if you did that in the past, this would eventually happen. I think the most appropriate solution may be to disallow SELECT FOR UPDATE/SHARE on sequences ... so if you have a good reason why we shouldn't do so, please explain it. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
