Review comment:
I would prefer if we didn't introduce new production code just for tests
even if it is tagged. I guess you can reproduce the problem by creating
explicitly a query using the `RelBuilder` and execute it afterwards (see
examples in `EnumerableRepeatUnionTest`). An alternative would be to create a
test with a custom validator that does not rewrite calls.
