What is the best way to upgrade?  Use pg_dumpall (using 8.2's program), afterwards redirect that file into v8.2 via psql v8.2?

There are lots of ways to do this. My favorite is to bring a new cluster on port 5433 and then pipe data between them, roughly like this:

$ /path/to/7.4/pg_dumpall -p5432 ... | /path/to/8.2/psql -p5433 -qaf- >restore.log 2>&1
