By 'insignificant' you mean 'necessary to do any non-trivial real work'.

But in lieu of that, I'll take as much push down power as possible :-D. merlin -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
