Bug reference:      13582
Logged by:          John Zhu

PostgreSQL version: 9.3.9
Operating system:   Windows 7
Description:

Column type: timestamp without time zone
Data: 2000-10-12 11:21:12.345335

When import from ODBC, psqlodbc 9.03.0300-1 driver can successfully import
this data. However, when import using 9.03.0400 driver, the StrLen_or_IndPtr
will return SQL_NULL_DATA, however, the data is presented in the buffer.
Manually remove the microsecond part (e.g. 2000-10-12 11:21:12) will import
successfully.
Binding is using SQL_C_TCHAR type: SQLBindCol(hStmt, 1, SQL_C_TCHAR,
pBuffer, ColLength, ptrInd);
