Well, it tries --- there is logic in there that pays attention to the scan direction. Like I say, I don't know the extent of the difficulty. If we were to decide that it's unfixable, the right thing would be to have the planner stick a materialize node on top, rather than invent a specialized kluge for GIST. 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
