Dick,

   PostgreSQL's SQL used to have a 'monetary' type that was deprecated in
favor of numeric. The latter is specified with total number of significant
digits and the number of fractional digits. For example, numeric(10,2) would
specify 1000000.00 to 9999999.99. (Formatting in the usual monetary way is
up to the UI while the numbers are exact.)
