Can't install Postgres 9 on stock Bamboo AMI

The stock Bamboo AMI ami-e4399e8d is running Amazon Linux 2011.09; when I run yum install postgresql I get Postgres 8.4.

But my build requires Postgres 9, which isn't available except in Amazon Linux 2012.03. According to the Amazon Linux documentation http://aws.amazon.com/amazon-linux-ami/2012.03-release-notes/ I should be able to run yum update to upgrade to 2012.03, but when I do that on the Bamboo AMI it doesn't do anything.

How can I upgrade to Postgres 9 from a stock Bamboo AMI?

Lucas' answer got me on the right track. I did need to add a new yum repo, but it wouldn't work out of the box. This article explains what you need to do: http://blog.henrygis.com/2011/04/installing-postgresql-84-postgis-and.html

Running rpm -i http://yum.postgresql.org/9.1/redhat/rhel-6-x86_64/pgdg-redhat91-9.1-5.noarch.rpm installs a pgdg-91-redhat.repo file in /etc/yum.repos.d

The problem is that the file contains "$releasever" variables that insert the Amazon Linux version, e.g. "2011.09" instead of a valid RHEL version, e.g. "6.0".

This one-liner fixes the problem:

perl -pi -e 's/\$releasever/6.0/g' /etc/yum.repos.d/pgdg-91-redhat.repo

Hello Dan,

You can configure a new yum repo:

rpm -i http://yum.postgresql.org/9.0/redhat/rhel-6-i386/pgdg-redhat90-9.0-5.noarch.rpm

Them install the required package:

yum install postgresql91-server postgresql91-contrib

Start the service:
service postgresql-9.1 initdb

That doesn't work, either when I use the URL you provided or when I grab the RHEL6 URL from here: http://yum.postgresql.org/repopackages.php

The problem is that it knows it's running Amazon Linux 2011.09, and finds that it doesn't have a copy of Postgres for that version of Amazon Linux. (If I could just upgrade the box to Amazon Linux 2012.03, this would be trivial!)

Since this question didn't get a good answer, I've posed a separate but more specific question here: https://answers.atlassian.com/questions/80482/upgrade-bamboo-ami-to-amazon-linux-2012-03
