[Jumping in, because this was the first message of the thread I've seen]
Technically, the correct behavior by spec would be an
implementation-defined precision and a particular scale based on the
argument scales. So, having numeric(6,2)+numeric(6,2) return
numeric(65535, 2) is fine. Returning numeric(65535, 65531) isn't
technically, but I don't think this is an issue in the jdbc metadata
getting as much as an issue in the database proper.
