Hi, The latest foreign-join pushdown patch allows fdw_scan_tlist to be set to a targetlist even for simple foreign table scans. However, since I think we assume that the test tuple of a foreign table for an EPQ testing, whether it may be copied from the whole-row var or returned by the RefetchForeignRow routine, has the rowtype declared for the foreign table, ISTM that EPQ testing doesn't work properly in such a case since that the targetlist and qual are adjusted to reference fdw_scan_tlist in such a case. Maybe I'm missing something though.
I don't understand custom scans/joins exactly, but I have a similar concern for the simple-custom-scan case too. Best regards, Etsuro Fujita -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
