In a former lifetime I worked with databases involving amounts of
different currencies, and I didn't find type money useful for that
either. But I think that's a specialized requirement and we'd be
unlikely to consider putting a type that *is* useful for that into
the standard distribution.
I think the money type has very simple, limited goals: give me a numeric
column that has I/O format determined by the current LC_MONETARY setting.
Sure, that doesn't solve every money-related problem, but it would have
usefulness enough to justify the limited amount of implementation effort
involved. The issues with the current implementation aren't really
related to that, they are related to a poor choice of underlying
representation.

If no one steps up and fixes it, eventually it will be.
