As Slava mentioned, you can use Compose.io. It requires using an SSH tunnel, though, which is a little tricky in Heroku. Here's a tunnel script I made to simplify this:

In particular, it reads the entire SSH private key as an environment variable, so you don't need to commit the key to the git repository.
