Yes, a certain test is important and I'm glad we've (almost) achieved it. ISTM we can say if not in KnownAssignedXids then check pg_subtrans. If not in either then report error. May need to add info to the abort record to check xtop also. -- Simon Riggs www.2ndQuadrant.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
