I run this SQL in PostgreSQL throw ERROR: operator does not exist: integer > text: 

So maybe this SQL is not valid too.

> When I try to design some unit tests for CALCITE-4742. I found Calcite can't handle NULL very well in some subquery.
> For example: 
> {code:java}
> select 1 in (values(null),(null))
> select 1 > some(values(null),(null))
> {code}
> This SQL should return NULL. But throw the runtime exception.
