Is there any reason why we don't just leave money in?  I know that NUMERIC
and DECIMAL will handle money amounts but the money type does a few
extra things related to locale, even if we remove the currency symbol
and perhaps we should leave that in if people are expected to use the
new types.  It also determines whether the comma or period is the correct
separator, puts separators in the correct place and determines where the
decimal point goes.  Also, check out what the following does.
   select cash_words_out('157.23');

Althugh there appears to be a bug in that function that chops the last
character from the output.
