Money should stay. It is the only fixed point integer based numeric
that comes with the database. Should a non locale dependent fixed
point type that offers the same performance come along, then you have
a good argument to deprecate.
numeric is definitely a dog which the fundamental problem IMNSHO. I'm
guessing optimization paths are going to revolve around utilizing
binary integer ops in cases where it's known to be safe to do so.
