Note MangoDB is a stateless proxy as such you can use it with any PostgreSQL setup. For example you should be able to use it with Amazon Aurora PostgreSQL as backend which has HA built in

If you are using the cloud then you can just use DocumentDB.

Which is the same proxy on top of PostgreSQL if I remember correctly. :) But MangoDB is cloud-agnostic. I imagine it has the same limitations as DocumentDB or more.

But then you have to use DocumentDB.

It depends. With MangoDB you can test on your laptop with PostgreSQL and deploy to Production to Aurora... or any other PostgreSQL compatible DBaaS.
