Thanks for the walk through with this.
I am having one issue with the check clusters step & hoping someone might be able to point me in the right direction.

When I try & run the check cluster step it fails and I get an error:
"Connection to database failed: could not connect to server: No such file or directory
Is the server running locally and accepting connections on Unix domain socket"

Are there any changes or issues with the postgresql.conf or pg_hba.conf that may cause this?
