PreparedStatement.setBinaryStream() will now stream data directly to the
server with no additional heap storage needed. setBytes() takes a copy
of the bytearray it is given, but otherwise behaves like setBinaryStream().
ResultSet still stores the whole value on heap. To avoid this requires
protocol modifications.
