> In the current implementation, some operators, such as `LogicalProject` and `LogicalFilter`, can be directly accessed by `Relshuttle`, while others, such as `LogicalCalc` and `LogicalWindow`, cannot be accessed directly. `RelShuttle` is a very important tool class. Usually, we will do equivalent transformation of relational algebra in the process of relational algebra optimization. This PR will cover the method of the operator visit `RelShuttle`, and the specific operator can be accessed directly by visiting `RelNode`.
