> Components: SQL
> Affects Versions: 3.1.0

> Priority: Major

> UnionExec requires its children's columns to have the same order in order to merge the columns. Currently, the physical rule `RemoveRedundantProjects` can pass through the ordering requirements from its parent and incorrectly remove the necessary project nodes below a union operation.
