Review comment:
Maybe, `cachedQuery` is better than `cachedTempView`?
For me, `cachedTempView` sounds like the following.
```sql
CREATE TEMPORARY VIEW tempView AS ...
CACHE TABLE tempView
```
We can rename this from `cachedTempView` to `cachedQuery` first. Then, we
can add a new test case for the real cached temp views of the above SQL case
before line 496.
