The General Bits newsletter has a few examples that might be helpful, even if they're not quite what you're after: http://www.varlena.com/varlena/GeneralBits/109.php http://www.varlena.com/varlena/GeneralBits/4.html There are sure to be some examples in the list archives -- just search for "create aggregate": http://archives.postgresql.org/ If these links don't help, then please post more details about what you're trying to do and what trouble you're having. If you have any code that doesn't work the way you want but that helps show what you're after, then go ahead and post it with an explanation of what it does (or doesn't do) and what you'd like it to do (or not do). -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
