You're going to have to pass metadata down, or change your queries to
explicitly cast the parameters in the SQL itself. The driver has exactly
the same problem as your code does -- with the v3 protocol it needs to
provide a type for the parameter, but if it's just provided as a string
the only type it can assume is text..
