FW: ERROR: Bad numeric input format '.' on insert or update of numeric column with a zero value

ODBC driver version: 07.03.0100 (ODBC 3 driver)
PostgreSQL database version: 7.3.2
Error message: ERROR: Bad numeric input format '.'

When I attempt to add or update a a row with a numeric(15,2)
column with a value of 0 (zero) or null, I get this error
message. If I change the value to anything else (.01, 1000), the
insert and update work.

Using psql, I am able to insert and update rows with numeric
values of 0 without an error.

If I drop back to the psqlodbc legacy 2.5 driver, I do not get
the error.

I get the error when using the Unicode (beta) driver and the ODBC
3 driver.

My application uses VB6 ADODB recordsets with MDAC 2.7.

For a test case, it should be pretty easy to duplicate. Create a
table with one numeric(15,2) numeric column. Use psql to insert
a row with a value of zero for the column. Now try to do the
same thing through psqlODBC ODBC 3.0 driver and you'll get the
error. If you try to update that row in that table with a value
of zero, you'll get the error as well.
