There are some differences among odbc drivers about the handling
of SQL_C_NUMERIC data.
Please note that psqlodbc driver ignores the precision or scale
specified in SQLSetDescField() calls. Please set the precision and
scale of SQL_NUMERIC_STRUCT data itself.
Anyway please add the following statement to rebind the data.
SQLSetDescField(hdesc, 1, SQL_DESC_DATA_PTR, ..);
