## Which issue does this PR close? - Closes #22678. ## Rationale for this change `ProjectionExprs::project_statistics` uses `std::mem::take` to move an input column's `ColumnStatistics` into the output when given a direct column reference. This means if the column is referenced again (either directly or in a `CAST` expression), the statistics are `Absent`. The simple fix is to just `clone` instead of `take`. This pattern crops up in TPC-DS q54, which includes a CTE that projects both `d_date_sk` and `CAST(d_date_sk AS Float64)`, but it's a more general bug. ## What changes are included in this PR? * Fix bug * Add unit tests ## Are these changes tested?
