Answer a question

How do I install Postgresql 11 on Amazon Linux 2018.03 (specifically, not AMZ Linux 2) on Elastic Beanstalk?

I want to install a package and not manually build a binary. If an autoscale machine boots and has to build the entire PG binary, it'll take significantly longer on a t2/t3.micro.

I'm looking for pg_dump.

[Edit] Making more verbose, explain why building does not work for my situation.

The key was the PGDG is no longer available to Amazon Linux's yum since 9.3 so the individual pieces must be installed.

  # Remove old Postgres
  yum remove -y postgresql postgresql-server

  # Install Postgres 11
  yum install -y https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-6-x86_64/postgresql11-libs-11.4-1PGDG.rhel6.x86_64.rpm
  yum install -y https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-6-x86_64/postgresql11-11.4-1PGDG.rhel6.x86_64.rpm
  yum install -y https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-6-x86_64/postgresql11-server-11.4-1PGDG.rhel6.x86_64.rpm

[edit] Replace the 11.4 in each link above with any version you need available at https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-6-x86_64/
