timestamp as varchar(23)

Hi,

I'm trying to get some "timestamp without time zone" column's value as a
varchar(23) value.

The SQLBindCol() function is used for this purpose in my C++ app.

However the result string doesn't contain milliseconds part at all while
the real column's value contains it ('2007-12-23 10:00:01.123' for
example).

After SQLFetch() the result's buffer contains '2007-12-23 10:00:01'
only.

The same program works fine with a MSSQLServer database so I cannot
suppose that there is something wrong in my app.

OS: WinXP SP2

"PostgreSQL 8.3.0, compiled by Visual C++ build 1400"

ODBC Driver: PostgreSQL Unicode 08.03.01.00

Additional connection string settings:

ByteaAsLongVarbinary=1; TextAsLongVarchar=1; MaxVarcharSize=8000;
BoolsAsChar=0; BI=-5; LFConversion=0; LowerCaseIdentifier=0;

How can I get "milliseconds part" in this case?

Thank you.
