Looking for good PostgreSQL hosters

I am looking for service providers that offer postgresql hosting.

One requirement, cheap but reliable (if there is any such thing).

It will be good if they can run different versions simultaneously (on different
ports of course)

If they offer versions of apache, php, mysql etc simultaneously it will be good.

I am getting rather tired of having to manage different versions systems in
parallel on my own servers and I am looking for provider who can do it all,
cheaply of course.

Perhaps I should bite the bullet, get a powerful dedicated server and run some
VMs, but I just hate to manage servers myself
