Why? pgbackrest does a great job managing WALs and data backups, keeping
everything consistent.

More importantly, during restore, pgbackrest assumes that all the WALs will
be where it thinks they are. Thus, while the backups *might* work,
restores would fail.

pgbackrest is not pg_basebackup; do not try to make pgbackrest act like
pg_basebackup.
