Review comment:
I think we need it. We have an instance of `QueryState` stored on the
`DriverContext`, and we have the same `QueryState` instance stored on
`SessionState` as well. If I remove the `QueryState` just from the
`SessionState`, we will end up with some dangling resources on the `QueryState`
bound to the `DriverContext`.
