What's the best way to install postgres-server 9.6 on Amazon Linux without building from source? I tried running rpm -i https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-6-x86_64/pgdg-ami201503-96-9.6-2.noarch.rpm to install the version listed on https://yum.postgresql.org/repopackages.php, and it installed without errors, but I still don't have service postgresql, or psql, or a postgres user. What did I miss?
