Just realised that this occurs again because the call to RecordKnownAssignedTransactionIds() was removed from xact_commit_abort(). I'm guessing you didn't like the call in that place for some reason, since I smile while I remember it has been removed twice(!) even though I put "do not remove" comments on it to describe this corner case. Not going to put it back a third time. -- 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
