Firstly, there's a README specifically for Debian in the postgres
packages, I suggest you read it, it has lots of information about the
way Debian has it setup.

Is there still a server running, or not? If not, delete to pid file.
That should work better.

No, that's normal. One is maintained by the postmaster, the other by
the init script.

How did you create that structure? If you did an initdb then it's
expected, some postgres initdb doesn't know about clusters. If you use
used pg_createcluster I beleive that should have been taken care of. In
either case I think they're harmless (if confusing).

If you make sure the server is down, you should just be able to delete
the pid file and upgrade...

Have a nice day,
