restore a database from file-only backup of /var/lib/pgsql/

I need to restore some data from yesterday into my postgres database. I only have a filesystem backup each night so I have the full contents of /var/lib/pgsql which contains data, base, global etc. etc.

How do I copy my backup database folder into my currently running or maybe a spare server so that I can query yesterdays data to export back into the current db?

I think my databse is /var/lib/pgsql/data/base/156814 and my backup is on /mnt/buffalo/daily.0/var/lib/pgsql/data/base/156814

Please please can someone help it's pretty urgent!

Thanks in advance

You can copy data directry on same version of server(OS platform included), but data will be damaged a bit.

you can start another postmaster running but define the environment variable PGDATA to point to your backup data files.
You can then dump data using pg_dump
