How not to use rpm owner/group info on unpack?

I was debugging an rpm problem and pulled my hair on this:

As root, both:
rpm2cpio file.rpm | cpio -idv
and
alien --to-tgz file.rpm ; tar xvzf file.rpm

unpack the package but lose the owner/group info for files.

Yet, installing the rpm on a system does use the right user/group info.

Argh, lost half a day on this :(

What is the proper way to unpack an rpm without losing the user/group info 
(i.e. without installing it and without relying on an rpmdb, just unpacking
its files with proper perms).

Thanks,
Marc
