 - [x] **`REPLICA IDENTITY FULL` enforced** — `add_table()` always issues `ALTER TABLE <src> REPLICA IDENTITY FULL`. The flush path has no TOAST-unchanged fallback: buffer table has no `{col}_unchanged` columns, appender rows are narrower (ncols not 2×ncols), and TOAST resolution is gone. Any `col_unchanged = true` in WAL (source identity changed after add) surfaces as a hard flush error triggering the existing backoff retry path. Trade-off: higher WAL volume on source.
