Hi,
I've stumbled into a bug, it seems the driver is not able to
retrive money data type from the db properly unless a getString
is used.... unfortunately in my case the code does not know
what kind of attributes is reading, and it uses getObject instead,
getting back an exception.
Running the attached code all I get is:
Exception in thread "main" org.postgresql.util.PSQLException: Il valore
«1,000.00» non è adeguato al tipo «double».
at
org.postgresql.jdbc2.AbstractJdbc2ResultSet.toDouble(AbstractJdbc2ResultSet.java:2645)

org.postgresql.jdbc2.AbstractJdbc2ResultSet.getDouble(AbstractJdbc2ResultSet.java:2032)

org.postgresql.jdbc3.AbstractJdbc3ResultSet.internalGetObject(AbstractJdbc3ResultSet.java:39)
at
org.postgresql.jdbc2.AbstractJdbc2ResultSet.getObject(AbstractJdbc2ResultSet.java:2348)
at PgMoneyIssue.main(PgMoneyIssue.java:15)
(translated from italian, "the value 1,000.00 is not adequate for the
type double". Not sure if the problem is locale dependent, since it has
been reported as a GeoServer bug by a user living in USA, and I then
tracked it down to this issue with the driver).
I looked for a bug tracker but could not find one, so here I am, posting
the bug report to the ml.
Contact me back if you need any further information
Cheers

/*
To run this example run the following sql:
CREATE TABLE testmoney (
id serial,
cost money NOT NULL
);
INSERT INTO testmoney (id, cost) VALUES (1, '$999.00');
INSERT INTO testmoney (id, cost) VALUES (2, '$1,000.00');
INSERT INTO testmoney (id, cost) VALUES (3, '$10,000.01');
and then fix the connection paramters
