If this stuff is willing to do so, you may have your reasons, but even
if you wish to locate both pg_wal/ and the prefetch path in the same
partition, I don't get why it is necessary to have the prefetch path
included directly in pg_wal? You could just use different paths for
both. Say, with a base partition at /my/path/, you can just have
/my/path/pg_wal/ that the Postgres backend links to, and
/my/path/wal-g/prefetch/ for the secondary path.
