if any body work on oracle .. he can right any query in any database :)Query maybe. but you were asking about functions. ANSI SQL is a pretty good standard for most normal dbs nowadays. But the procedural extensions differ more. Therefor you should go to a postgress forum to ask there. Or upgrade your database to oracle.
