The documentation for pg_replication_slots previously mentioned only max_slot_wal_keep_size as a condition under which the wal_status column could show unreserved or lost. However, since commitbe87200, replication slots can also be invalidated due to horizon or wal_level, and since commitac0e33136a, idle_replication_slot_timeout can also trigger this state. This commit updates the description of the wal_status column to reflect that max_slot_wal_keep_size is not the only cause of the lost state. Back-patched to v16, where the additional invalidation cases were introduced.
