LGTM but I think we should add some tests. If someone destroys this we can trigger it

The bug here is due to Tuple's fields_name is defined as String, resulting in missing quote-related information. We should fix this by defining fields_name as Identifier. In order to solve the problem of current use, we can merge this PR first and make further modifications later.
