Upgrading postgresql-8.0 to 8.1

Sorry, that's "pg_upgradecluster 8.0 main", not 8.1

I'm far from guru but one method that might be 'safe' would be to use pgdump to
just dump the database, stop 8.0 and load everything into 8.1.

If anything goes wrong, you have all the data in a file so you can at least fix
it. I would expect this to be issues with creation of tables/databases at most
and not something you have to fix on every line.
