How can I enable PostgreSQL 9.0 support in PHP on my Amazon EC2 instance? I'm running the free 32 bit Linux Micro instance. I've installed PostgreSQL 9.0 by following these instructions http://www.imperialwicket.com/aws-install-postgresql-90-on-amazon-linux
If I install the php-pgsql package using yum, it only supports PostgreSQL 8.4.7. Ultimately I'd like to use PostgreSQL 9.0 through PDO.
