Well, there are AMs around already that can't index nulls: hash is one, and GIN was one until an hour ago. The question though is whether anything outside the AM needs to know about that behavior. Between amclusterable, amsearchnulls, and amoptionalkey, I believe that we have quite enough flags already to cover what anything else actually needs-to-know about the AM's behavior. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
