BTW, after reflecting a bit more I'm less than convinced that this
datatype is completely useless. Even if you prefer to store currency
values in numeric columns, casting to or from money provides a way to
accept or emit values in whatever monetary format the LC_MONETARY locale
setting specifies. That seems like a useful feature, and it's one you
could not easily duplicate using to_char/to_number (not to mention that
those functions aren't without major shortcomings of their own).
I personally find that one of the money type's missfeatures, since the
currency symbol does not vary just per language/locale but also for
which currency you are working with. For databases with multiple
currencies the output format of money is just confusing.
