If you're in a hurry, just install 8.3 from source and run postmaster -D
/path/to/data/files (be sure to choose a nonconflicting port).  Then you
can connect to it with pg_dump and get the data out and into the 8.4
installation.

Oh, make sure you keep an eye out for the socket directory too ...
default PG places sockets in /tmp whereas Debian places them in
/var/run/postgresql.  Just in case.
