Fully agree with this sentiment it's very much our focus and goal at Crunchy Data with one big thing I'd add-great support.

I recall seeing them crop up in the early days of building and running Heroku Postgres, they were a very very early managed service provider. To my knowledge they never seemed to grow to massive scale but were a steady business (though I don't know any of the details for sure). That they were still around for over a decade is a testament from a lot of others.
