I obtained a database through my school, and I have the port number (though I'm not sure where that's needed on the wp-config file, if at all), database name, username, password, and host. I have been given a PostgreSQL account with these, as that is what is supported at my school. I was given this link for a PG4WP plugin and I followed the install instructions:
I originally was using WP 3.3.2, but I kept getting this error: "Error establishing a database connection." I went & downloaded 3.2.1, as the plugin said that was the latest compatible version, figuring it was that. It wasn't. I've keyed in all information correctly on the wp-config file (I manually tried to do it after the 5 minute install wasn't working), and I'm still getting this database connection error. I'm thinking something went wrong with the PG4WP plugin, but I followed the directions and I'm not sure what I'm doing wrong/where to go from here.
