You want to pg_dump (or pg_dumpall, but pg_dump'ing each database
would give you a bit more control) and load the resulting script
into the new server.

If possible, use the 8.2 pg_dump to do this, as it's a lot more
featureful than what came with 7.1 --- in particular it will
handle blobs better.

I have a vague recollection that there are some corner cases that
changed in the COPY data format since 7.1.  If you are having
trouble with getting the data reloaded, try using the -d option
to pg_dump.
