Have you installed the dm-postgres-adapter gem?

For instructions that mention this gem check out: http://twitter.com/dkubb/status/15742240677

Thanks. I've rolled back to using Heroku's stock dm gem for now but if I move forward again I'll do what you suggest.

It should be easy to bundle the gems with your app using Heroku's Bamboo system.

Unfortunately Heroku's stock DM gems are horribly out of date. I would not recommend them for any serious development atm.
