I was reading this:
Step 2 says "Install the certificate in your operating system", but I am able to connect with
psql without doing anything, and when I do, it says
SSL connection. Without the servers certificate, how can it do this? Where are public certificates to be kept for a client to check? I've seen things talking about ~/.postgresql, others saying with the rest in /etc/ssl, but I don't see Amazon's anywhere on my system.
