When some slots are invalidated due to the max_slot_wal_keep_size limit, the old segment horizon should move forward to stay within the limit. However, in commit c6550776394e we forgot to call KeepLogSeg again to recompute the horizon after invalidating replication slots. In cases where other slots remained, the limits would be recomputed eventually for other reasons, but if all slots were invalidated, the limits would not move at all afterwards. Repair. Backpatch to 13 where the feature was introduced.
