This patch release improves native append performance and adds helpers for sequence-backed append workflows.
Highlights:
- Fixed quadratic LIST/MAP append encoding for large nested batches.
- Reused Ecto append temp tables for
RETURNINGpaths. - Added sequence allocation and catalog-backed column sequence lookup helpers.
- Added primary-key/default metadata helpers.
- Added explicit direct append shape selection with
append_shape: :columns | :rows.
