It was difficult to dicide which is reaaonable but I named it
after wal_keep_segments because it has the similar effect.

In bytes(or LSN)max_wal_sizemin_wal_sizewal_write_flush_after

In segmentswal_keep_segments

But surely max_slot_wal_keep_segments works to keep disk space so
bytes would be reasonable.
