## Which issue does this PR close? Related to https://github.com/apache/datafusion/issues/14563 (probably more prs to come) ## Rationale for this change Now, when normalizing the column, we always generate `plan.using_columns()` which is recursive and very expensive - and [may not be needed](https://github.com/apache/datafusion/blob/980931c5a70b8b08c918195803145f64f1ec901f/datafusion/common/src/column.rs#L224) if column is already normalized ## What changes are included in this PR? Exit early if column already has a relation set. Also, set the relation when `with_column_renamed` is called ## Are these changes tested? Extended a test to assert references ## Are there any user-facing changes? No -- This is an automated message from the Apache Git Service.
