This might be nice to have, but I don't think it's necessarily a prerequisite for a committable patch. For that, I think we just need something that uses the dispatch mechanism to avoid the overhead in the normal case. However, as this is a substantial redesign and there are 4 days left in the CommitFest, I am going to mark this patch Returned with Feedback for now. ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
