The "money" datatype is deprecated:
http://www.postgresql.org/docs/8.2/static/datatype-money.html
Not sure why that notice doesn't appear in the 8.3 docs.

they are easy enough to add and also easy for you to implement
yourself for the time being (read the section on "custom types" and/or
imitate an existing PG type from postgres.py). If you're interested,
that would make a patch for us to implement these new types.
