If your example there is correct that XMLTABLE can be called as a plain function in a SELECT list, then I doubt that we want to tie anything about it to the RTE data structure. If anything, the case where it appears in FROM seems to need to be treated as a generic RTE_FUNCTION case. I've been trying to avoid getting involved in the XMLTABLE patch, mainly because I know zip about XML, but maybe I need to take a look. 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
