> when call `RelBuilder.in` to create an `IN` predicate with a list of varchar
> literals which have different length, generated `RexNode` are expected.
> for example, ranges parameters are `b.literal("CLERK")` and `b.literal("A")`
> Generated `RexNode` seems to be unexpected because it would cast 'A' to
> char(5).
