>
> `SetOpConverterRule` creates a rowType produced by set operation by means of
> `TypeFactory::leastRestrictive`. This should not be necessary because types
> of rows returned by inputs to set operation should be coerced at the
> validation stage by `SqlValidator`/ SetopOperandTypeChecker`.
> Remove calls to `TypeFactory::leastRestrictive` from `SetOpConverterRule` for
> both colocated and map/reduce versions of operators and use `rowType`
> returned by a set operator node.
