> `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.
