Thanks. I'm trying to do your option (a) -- defining the function return type. But I want to do this by referring to an existing table type -- which I know the returned fields must match -- rather than laboriously retype the field definition list for that table. The problem is that I can't make the database accept the table type as a field definition list, when that seems like a perfectly sensible (and in this case much more convenient) way to define the fields that will be returned.
