Helpful feedback, we do have a development plan for $99, but it's not really intended for production workloads. If you only have 10 GB of data we'd heavily recommend going with something like RDS or Heroku Postgres. At that amount of data single node Postgres works great.
RDS is not single node - its multi-AZ replicated. And that's what we are paying 300$ instead of 99$ for. Imagine.. RDS is literally the ONLY place where you can buy a 10 GB data multi-AZ replicated, snapshotted and managed postgresql. Its pretty much a monopoly, now that Google seems to have officially closed the book on ever supporting postgresql.
I would be hesitant to say that this is a fact.
