Agreed. Monitoring an exclusive backup is very helpful. But I wonder
why we want to monitor non-exclusive backup. Is there any use case?
If we want to monitor non-exclusive backup, why not pg_dump backup?

If there is no use case, it seems sufficient to implement the function
which reports the information only about exclusive backup.
