Since we may need some further modification in the TreeNode, I'd like to
separate that from this part and do that in `createPlanForView()`. I'm not
sure, we can discuss this further.
For case problem, Hive stores the table name with the original text without
turn it into lowercase. And I think it is not necessary to convert that here.
We can push this to reference resolving, as it already was there.
