### What changes were proposed in this pull request? Add a new trait `ReferenceAllColumns ` that overrides `references` using children output. Then we can skip it during rewriting attributes in transformUpWithNewOutput. ### Why are the changes needed? There are two reasons with this new trait: 1. it's dangerous to call `references` on an unresolved plan that all of references come from children 2. it's unnecessary to rewrite its attributes that all of references come from children ### Does this PR introduce _any_ user-facing change? prevent potential bug ### How was this patch tested? add test and pass CI Closes#40154 from ulysses-you/references. Authored-by: ulysses-you <ulyssesyou18@gmail.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com> (cherry picked from commit db0e822) Signed-off-by: Wenchen Fan <wenchen@databricks.com>
