If the backup includes pg_xlog and pg_clog, as well as all of the
database metadata files, then whatever portions *are* included are
likely to be somewhat usable.
The portions not included in the backup will obviously not be usable.
But supposing your backup does not include *all* metadata (e.g. -
pg_catalog), pg_xlog and pg_clog, then it is unlikely that you'll be
able to recover *anything at all* from it.
The intent is that filesystem backups only work for complete backup
and restoration of an entire database cluster.
Backing up *part* of your filesystem is Not Recommended in the
documentation. If you set a policy of doing so, you have to accept
that you are doing this contrary to documented recommendations, and at
considerable peril to your data.
