I found mention on Google about Debian's wrapper scripts, the man page
for pg_upgradecluster isn't so helpful explaining what it's doing.
I ran pg_upgradecluster, it complained the cluster already existed -
the install created a new 9.1 'main' when it installed.
So the process was to do the following:
1) # pg_dropcluster --stop 9.1 main
2) check any applications accessing postgresql are stopped
3) # pg_upgradecluster -v 9.1 9.0 main
Then check my applications worked accessing the database, which they
did.
cheers,
