In Yii [tests](https://github.com/kadishmal/yii/commit/c0b90c73bba4c1f2ce630085921d2400ef53628f#L11R97) the default behavior was to compare the precision of `INT` columns with `11`, so I set the default precision to 11.

Another options is to remove this line, and set `null` in tests where they compare `INT`'s precision.
