Hello. Since release 8.2 row comparisons work well - thanks! It would be nice if MIN and MAX aggregate functions could operate on row values, so I could write in SQL:
SELECT MIN(ROW(a, b, c, d)) FROM table to find extreme value of ordered set of columns. It should not be hard to implement, please. I'm looking forward to release 8.4 which will introduce window functions. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
