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
This obviates the intermediate dump file, which can be large.
As a precaution, I remove the PATH elements that locate pg (thus requiring that I specify the full path) and I unsetl PG* variables.
