Whoops!   Didn't want to confuse you.   What I meant was, a PgSQL
function "Datediff" could be easily *written*, except that it would
need quoted identifiers, different from the T-SQL function.   If anyone
on this list has written a DateDiff, please post!

Cool!   Glad that you found something that would work for you.
