Hi Orlin, Heroku could definitely use a rollback feature - I hope it's on their list ;)
When I started using Heroku I asked about it on this list, and people advised me to tag my releases and then push the previous tag if I needed to rollback. I implemented that and write a blog about it a few months ago: http://casperfabricius.com/site/2009/09/20/manage-and-rollback-heroku-deployments-capistrano-style/ Obviously this means that I don't deploy with "git push heroku" but rather with "rake deploy". Since then, I have improved my Heroku deployment script a bit. The current version is here: http://gist.github.com/307479 Hope this helps.
