Can't get rails app to start on heroku

I'm trying to deploy a rails app to heroku, but keep getting the following error. I'd have thought that managing the postgres gems would be something heroku would handle.

I've tried everything I can think of short of installing postgres on my local machine, which I'd need to do if I wanted to install the postgres gem. There's also no gem called activerecord-postgresql-adapter... I'm guessing this is the standard adapter that comes with rails??

Any thoughts on how to fix this?

Upgrade your Gemfile to Bundler 0.9 and add the pg gem. Easy as that.
