修复逻辑复制槽的 restart_lsn 可能后退的情况（Masahiko Sawada）§
之前，重启逻辑复制有时会导致复制槽的重启点被重新计算为一个比 pg_replication_slots 中先前公布值更旧的位置。这是有问题的，因为例如 WAL 文件可能已经根据较新的 restart_lsn 值被删除，在这种情况下复制将无法重启。
避免在 pg_rewind 过程中删除仍然需要的 WAL 文件（Polina Bungina，Alexander Kukushkin）§
\n之前，在不巧的情况下，pg_rewind 可能会从被回退的降级主库中删除重要的 WAL 文件。特别是当这些文件已经被标记为待归档（即其 .ready 文件已创建）但尚未归档时，就会发生这种情况。此时新提升的节点不再拥有这些文件，因为它们已经被回收，但降级节点的恢复可能需要它们。如果 pg_rewind 将它们删除，恢复就不再可能了。
