I don't think it's quite that bad: the patch doesn't touch scan/join planning very much, so for instance I doubt that the pending unique-joins patch is completely broken. But yeah, anything having anything to do with planning of grouping/aggregation or later stages is going to need major revision to play with this. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
