Review comment:
> If you define extractors for the mixed case, I think we need to make
them more general for extracting more complicated cases, mix of cube/rollup,
mix of rollup/grouping sets, ...
Since current code only support one cube/rollup expr, so I just support one
cube/rollup expr.
Since other engine support mixed case, IMO, we should and we can support
these feature and it's compatible with the previous behavior。
I will update this later.
