Install PostgreSQL 10 on Ubuntu

This is a quick guide to install PostgreSQL 10 - tested on Ubuntu 16.04 but likely can be used for Ubuntu 14.04 and 17.04 as well, with one minor modification detailed below.

(Optional) Uninstall other versions of postgres

To make life simple, remove all other versions of Postgres. Obviously not required, but again, makes life simple.

dpkg -l | grep postgres

	class User
	has_many :tickets
	end

	class Hall < ActiveRecord
	has_many :movie_sessions
	end

	class Movie < ActiveRecord
	validates_presence_of :name
