You're reading something into the documentation that's not there.
Postgres doesn't have an explicit notion of precision and scale
for type money; those concepts are specific to type numeric.
I think the information_schema views will present made-up, hard-wired
values for the float and integer types as well, but they don't for
money, since its range is locale-dependent.
