Hmm ... you are right that this isn't as simple as an ereport(ERROR), but I'm not sure it's impossible. We could for instance put the backend into skip-till-Sync state so that it effectively ignored the next command message. Causing that to happen might be impracticably messy, though. I'm not sure whether cancel-transaction behavior is enough better than cancel-session to warrant extra effort here. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
