> Should we get Column's relation for Alias in `to_field`? I think we should directly use the relation from the Alias itself, as that is the purpose of an Alias expression. After an expression is rewritten, by adding an Alias we can ensure that the result of `to_field` remains the same, including the qualifier and name, thus maintaining the schema unchanged. -- This is an automated message from the Apache Git Service.
