Have you checked what's in those WAL archives? You can do that with
pg_waldump. My guess would be that your vacuum is probably more active
than in the version 11. However, that's just a guess. You can also turn
on WAL compression. Be aware that compression will reduce disk
consumption at the expense of CPU consumption.
