[urgent]need help transferring database to another server

our postgres server died yesterday and i need to retrieve the data from
that server to another one.  the server was running postgres 6.5 and i need
to move it to another server also using postgres 6.5.

i am unable to do a pg_dumpall for some reason, so i was wondering if i
copy the data directory from server to another, will the new server be able
to read the data and i can dump the data?

any help would be appreciated.

It _should_ work.

Note, however, that pre-WAL versions of PostgreSQL are not really
crash safe.  There is a possibility that your data is in an
inconsistent state.

Are you _really_ stuck with 6.5?  I'd strongly suggest you
investigate upgrading after you recover your data, if you can.

I should have qualified that: assuming the endian-ness and other such
attributes of the systems are the same.  You can't do that from, say,
Linux to Solaris.  Your best bet is to go to a system as similar as
possible.
