RDS pricing appears competitive to Heroku's dedicated databases. It's hard to compare them directly since RDS separates instance type, on-demand and reserved instances, provisioned storage, replication (crossing availability zone boundaries), and number of requests. Heroku on the other hand provides a fixed amount of storage (and one that's twice the max one can provision for RDS), a mix of instance types, and a connection cap limit. It's not clear if Heroku provides multiple availability zone instances similar to RDS. Ignoring provisioned storage and request costs one can have a small on-demand RDS instance for ~$80/month. Heroku's instance (RAM/CPU) equivalent (Ronin) is $200/month.
