We haven't had that discussion AFAIK, and definitely should. First glance suggests they could coexist peacefully, with proper coaxing. If I understand things properly, Jonah's patch filters tuples early in the join process, and this patch tries to ensure that hash join batches are kept in RAM when they're most likely to be used. So they're orthogonal in purpose, and the patches actually apply *almost* cleanly together. Jonah, any comments? If I continue to have some time to devote, and get through all I think I can do to review this patch, I'll gladly look at Jonah's too, FWIW. - Josh -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
