If you want a managed PostgreSQL instance CommandPrompt offers that as a service http://commandprompt.com/services/dedicatedhosting/ http://commandprompt.com/services/dedicatedhosting/ The issues with running a database in a shared environment are that you need dedicated hardware for performance, you do not want to be telling customers that you don't know why it takes 10 seconds to update inventory quantities only to discover it's someone else sucking up your disk bandwidth. And as Thomas points out the security considerations alone should kill the idea; it's possible for someone with administrative access to dump the contents of memory on a VM (how VM migration works) and at that point any private keys you are using to provide "transparent encryption", or any inflight customer business data is fair game.
