take a deeper look in your logfile
2011-11-12T20:43:37+00:00 app[web.1]: /app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.1.1/lib/active_record/connection_adapters/abstract/connection_specification.rb:71:in
rescue in establish_connection': Please install the postgresql adapter:gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.) (RuntimeError)
Is the cause of your problem.
Heroku provide PostgreSql - consequently you need to add the pg gem to your Gemfile - presuming you're using sqlite3 presently for development
group :development do gem 'sqlite3'endgroup :production do gem 'pg'endrebundle, commit and repush to Heroku and you should be fine.
