I was looking for hosted PostgreSQL and eventually wound up at http://elephantsql.com, with which I've been happy. I don't have a 'production' service in that I'm not relying on a DB to sell a service, like underpinning an app/website. But my DB is mission critical for knowledge management for my business, and I don't trust myself to manage the server properly. Nice to see competition in this space, and DO is a good one to be offering hosted databases - I'm happy with their other services too.
