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. If you have data in your previous version of postgres that you'd like to retain, then this is not recommended. Instead, you'll have to use pg_upgrade or pg_upgradecluster.

Let's build our own code reloader for Rails, shall we?

Require dependency problems

Run this inside rails/railties:

$ grep -rn "eager_load_paths" .

You should get the results from Rails::Engine::Configuration and Rails::Engine. As you know, each Rails application is actually a Rails::Engine and Rails::Engine::Configuration is that thing wrapped inside Rails.application.config block.
