This is mainly useful because the upcoming logical-decoding-on-standby feature adds further reasons for invalidating slots, and we don't want to end up with multiple invalidated_* fields, or check different attributes. Eventually we should consider not resetting restart_lsn when invalidating a slot due to max_slot_wal_keep_size. But that's a user visible change, so left for later. Increases SLOT_VERSION, due to the changed field (with a different alignment, no less).
