Complete redo engine for more resource managers
Currently the redo engine covers heap, heap2, and btree operations. Other access methods (GIN, GiST, BRIN, Hash, SP-GiST, Sequence) rely on full-page image (FPI) coverage for correctness.
Adding dedicated redo handlers for these resource managers would enable fine-grained delta tracking instead of storing full page images, reducing layer size and improving reconstruction performance.
