> A query which has a pattern:
> column IN (1, 1 + 1, 1 + 2)
> For the tuple, Calcite makes a plan like
> {code}
> UnionAll(all=[true])
>   UnionAll(all=[true])
>     Project(EXPR$0=[+(1, 1)])
>       Values
>     Project(EXPR$0=[+(1, 2)])
>       Values
>   Values
> {code}
> At execution, the schema of the recordbatch from scanning Values is [`ZERO`(BIGINT: OPTIONAL),  `*`(BIGINT: OPTIONAL)].
> The second column (i.e., `*`) is not supposed to be there.
