by the way -- backend protocol does not return numeric error codes
so ODBC driver cannot set SQLCODE's. (SQLCODE returned by ODBC driver is
always empty). So applications that use ODBC can not distinguish
for example, referential integrity errors from backend fatal errors or
errors in SQL statement. Of course, it is possible to examine
string error messages which are returned by backend by this is rather
hackish and there is no evidence that they will not change in future.
