Thanks for pushing this work forward. I ever tried (but failed) to find some similar functions in other DB products. This makes me confused about whether we should treat `[null, null, .., null]` as `null`. That is, to introduce `NullPolicy.ALL` or use `NullPolicy.NONE`? At least, current `NullPolicy.ANY` is wrong. Personally, I'm inclined to introduce `NullPolicy.ALL`, as it follows SQL standard.
