I copied my .csshrc to a new machine, and needed to add a domain suffix to the hostnames of 20+ VMs in my cluster config. All of my hostnames end in at least 2 digits (foo-bar-baz-01), so I:

1. Search for instances of 2 digits followed by whitespace.
2. Preserve the digits in a capture group.
3. Append the suffix to the capture group (\1)

Append domain suffix where none exists:

Search: ([0-9]{2})\s Replace: \1.my.domain.suffix

# Be sure to save your config files. Optional but I do:
sudo cp /etc/postgresql/9.3/main/postgresql.conf ~
sudo cp /etc/postgresql/9.3/main/pg_hba.conf ~

# Package repo (for apt-get)
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main" >> /etc/apt/sources.list.d/postgresql.list'

# Also probably optional but I like to update sources and upgrade
sudo apt-get update

TL;DR

Create a backup:

pg_dumpall > mybackup.sql

Perform the upgrade:

sudo pg_dropcluster 9.4 main --stop
