// reader where schema is available and could tell how to encode these.
// Currently reader doesn't maintain schema and there's no way to test it.

// func TestMediumblob(t *testing.T)
// func TestLongblob(t *testing.T)
//
// Tried testing Mediumblob and Longblob the same way, got this error:
// Error 1105: Parameter of prepared statement which is set through
// mysql_send_long_data() is longer than 'max_allowed_packet' bytes
//
// That is from the client trying to insert a massive blob. I guess that's good
// enough and I hope these types work too.
