> For instance, given the following query:
> {code:sql}
> SELECT t0.col0, t0.col1
> FROM
>   (
>     SELECT col0, col1 FROM tab
>   ) AS t0
>   INNER JOIN
>   (
>     SELECT col0, col1 FROM tab
>   ) AS t1
> ON t0.col0 < t1.col0 AND t0.col1 > t1.col1
> {code}
> we could still infer that col0 and col1 cannot be null for any of the inputs. Currently
we do not.
