Also, it's not very sensible to consider extensions of this sort unless we have ambitions of turning psql into a full-fledged scripting language, with conditionals and iteration at the very least. I do not want to go there. If you need scripting capability, there are lots of better tools out there already. 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
