I recently installed Ubuntu-17.10 and then discovered that Postgresql from the Pgdg repos is only supported on Ubuntu LTS releases (eg 16.04). However info on the internet said pg-10 could be installed from Pgdg zesty repo, which with some package version conflicts, I was able to do so and have a functional pg-10.1 install. However I need to upgrade to 10.3 and the normal "apt update; apt upgrade" does not offer 10.3. Also, doing a fresh install still installs 10.1. Is Pgdg 10.3 even available for ubuntu 17.10? How the heck does one upgrade to it?
