  PR Summary: What problem does this PR solve? Problem Summary: What changed and how does it work? When filtering columns, also skip generated columns that have dependencies on any of the skipped columns to maintain consistency and avoid reference errors in query planning. Another issue is that the predicate should also consider the dependency columns. Otherwise, we will miss some column information when building the analyze executor.
