You can either use pg_dump or do filesystem backups *with the postmaster
stopped*.  See the Administrator's Guide:
PG 8.0 will allow a third basic approach, on-line backup:

The "File system level backup" subsection in that chapter explains why
piecemeal copying of data files (which is what I understood Marcin to
say his friend did) doesn't work.  Add to that the issues associated
with a cross-version changeover (such as, usually, changes in system
catalog contents and layout), and I'm amazed that the thing appeared
to work at all.
