After thinking about this a little more, I realize that the problem for me
is not that the upgrade didn't go well. It's that I can't access my data
on 8.2. If upgrading the cluster allows me to access the data, great. If
I can access the data on 8,2, that'd be great, too, and then I can worry
about upgrading. It looks to me like the data is still there:

$ du -shc /var/lib/postgresql/8.2/*
308M /var/lib/postgresql/8.2/main
308M total
$ du -shc /var/lib/postgresql/8.3/*
30M /var/lib/postgresql/8.3/main
30M total
$

How can I see it? Why won't 8.2 start? Note that I get no message at the
prompt when trying to start 8.2.
