Hi Marc, Unlike the web tier, we don't believe it's possibly to do horizontal +infinite auto-scaling of SQL databases. That is reserved for distributable document databases like CouchDb, MongoDb etc that will undoubtedly become an important part of the web application space in the near future.
For now, Heroku provides seamless vertical scaling of our SQL database layer. It'll go from a shared db environment - like you see in our free beta - up to a dedicated server based on the largest high-cpu instance EC2 has to offer. Throughout all our tiers redundancy and failover is fully managed by our infrastructure, and you don't have to worry about it. Upgrading between the tiers is seamless and invisible as well. Hope this answers your question. We should be releasing more public info on this within a week or two.
