If you don't think this is a problem, Please add extra SQL unit tests in PR. (I
guess can't get the consistent result with PostgreSQL)

> There exists some inconsistency to infer type of Sarg RexLiteral.
> 1. The method `RexSargBuilder#getType` in `RexSimplify` using
> `rexBuilder.typeFactory.leastRestrictive(Util.distinctList(types));`
> 2. The methods `RexBuilder#makeIn` and `RexBuilder#makeBetween` using type of
> first ranges as Sarg RexLiteral's type.
> It's better to unify type inferring logical for Sarg RexLiteral.
> IMO, I think using
> `rexBuilder.typeFactory.leastRestrictive(Util.distinctList(types));` is more
> reasonable.
