Status of the `MATERIALIZED` CTE work after #25580 merged:
**Ready for review** (based on `main`, independent of each other)
- #26269 Make the materialized CTE nodes a first-class `LogicalPlan` variant
- #26270 Keep the output of a materialized CTE per run, not in the plan
- #26271 Report statistics, ordering and partitioning of materialized CTE
scans
**Draft, waiting on a base PR** (only the last commit is new)
- On #26269:
- #26273 Protobuf serialization
- #26274 Prune unused columns from the CTE body
- #26275 Push filters that all references share into the CTE body
- #26276 Decide automatically when to materialize a CTE
- On #26270:
- #26272 Release the output when the last scan finishes
I will rebase each draft and mark it ready when its base merges.
