Hi David,
I've never done this but I seem to remember seeing something about this
recently.
Firstly, I think you need 7.3.1 to do this.
You then have to create a 'type' as being a set of your table. You then
define the function as returning that type.
Sorry I can't be more specific, but as I said, I've never done it.
