Install PostgreSQL 10 on Ubuntu

This is a quick guide to install PostgreSQL 10 - tested on Ubuntu 16.04

Add PostgreSQL apt repository

The current default Ubuntu apt repositories (up to 02.05.2018) only have up to postgresql-9.5. To get 10, we'll add the official postgres apt repository.

• Ubuntu 16.04: sudo add-apt-repository 'deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main'
