OK I understand the issue now. Sometimes a `Project` is useful to avoid name conflicts. However, it should only be a problem in the analysis phase. We may have other rules that remove `Project` if it doesn't change the query schema. I think it's better to fix `RewritePredicateSubquery`, which kinds of re-resolves the column. -- This is an automated message from the Apache Git Service.
