With due respect, this sort of thing is rather difficult to get right
all at once. =A0I would suggest at some point having a modified MONEY or
maybe to avoid conflicts let's call it a CURRENCY datatype on
Pg-foundry where we can experiment and get these details right. =A0I am
thinking of doing a rough draft in SQL and PLPGSQL so that someone can
convert to C once everything works properly :-).

If folks are interested, I might make a simple approximation of this
that would require 8.4 or higher. =A0It might come in handy for
LedgerSMB too.....

Best Wishes,
