The calling FDW is supposed to do that; note the header comment. I'm not sure that it'd be an improvement to change the API spec to be "create_foreignscan_path has no intelligence, except that sometimes it will decide to override your rows estimate anyway; nonetheless, it takes your cost estimate as gospel". 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
