Sorry for the delayed review @watarukura -- I have been away. I don't think adding UNSIGNED as ColumnOption is correct -- it should be a data type instead

I think UNSIGNED is a DataType (not an option on the column definition)
Specifically you can do something like
mysql> select cast(x as unsigned) from bar;
+---------------------+
| cast(x as unsigned) |
+---------------------+
| 1 |
| NULL |
+---------------------+
