> CalciteMaterializer tries to rewrite query relnode with the star table in
> schema (the first one that fits). Utility function used is
> RelOptMaterialization::tryUseStar. Utility function should return null when
> it cannot rewrite relnode using star table, but instead it is returning the
> same relnode back. This is causing MV being assigned star table even when it
> is not required.
