> In 0.8, TypeCheckingVisitor works on the old logical plan, before it is
> translated to new logical plan. The TypeCheckingVisitor checks the types in
> expressions, adds casts and tracks lineage for identifying which load
> function's LoadCaster interface is to be used to convert bytearrays into
> other types.
> As the old logical plan is going away in 0.9, this functionality needs to be
> added for new plan.
