Fix cases where a logical replication slot's restart_lsn could go backwards (Masahiko Sawada) §
Previously, restarting logical replication could sometimes cause the slot's restart point to be recomputed as an older value than had previously been advertised in pg_replication_slots. This is bad, since for example WAL files might have been removed on the basis of the later restart_lsn value, in which case replication would fail to restart.
Avoid deleting still-needed WAL files during pg_rewind (Polina Bungina, Alexander Kukushkin) §
\nPreviously, in unlucky cases, it was possible for pg_rewind to remove important WAL files from the rewound demoted primary. In particular this happens if those files have been marked for archival (i.e., their .ready files were created) but not yet archived. Then the newly promoted node no longer has such files because of them having been recycled, but likely they are needed for recovery in the demoted node. If pg_rewind removes them, recovery is not possible anymore.
