With access to a 100% accurate external device database instead of the
existing .cache this is easy.
The --trustcache argument would be enabled by default on such a system.

This would actually just be something like 'pvs -o uuid <device>' with
a subtle modification so it notices there are no VG fields required
and so it doesn't attempt to access the VG metadata (which might
require accessing disks other than the one specified).
