During REPACK CONCURRENTLY, logical decoding keeps replication slot.restart_lsn pinned behind the oldest running transaction, which is often the long-lived REPACK transaction itself. As a result, old WAL segments are retained longer than necessary. This commit advances the replication slot each time WAL insertion crosses a segment boundary, so obsolete WAL files can be recycled while REPACK is still running.
