UnionRel returns the union of the rows of its inputs,
optionally eliminating duplicates.UnionToDistinctRule translates a distinct UnionRel
(all = false) into a DistinctRel on top
of a non-distinct UnionRel (all = true).AggInternalTranslator.RexGroupVariable and AggInternalTranslator.RexAggVariable objects

going to be.
