float8 and currency conversion

I'm trying to export some tables from MS Access 97 via ODBC. I'm using
psqlODBC driver 7.02.00.05.

Exporting tables through the ODBC connection works fine - until I get to
the tables that have currency fields.

The tables will still be exported if all the amounts end with 00 - i.e.
NOK 123,00 works fine. This is "translated" into 123 in my PostgreSQL
database.

The real problem arises when there's a non zero digit after the comma.
Like NOK 123,40
If I try to export a table containing a currencyfield like that I get the
following error;

ODBC--call failed.
ERROR: Bad float8 input format '123,4' (#7)

So obviously float8 isn't what I want to translate my currencyfields as.
What data type SHOULD be used - and how do I tell the ODBC link that I
want to use a different translation than float8..?

Thanx :)
