Can you point me to the list of cloud hosting services that support JVM + SQL (prefesably Postgresql)?

I know Heroku does that, but the pricing model for database is too jumpy, and I'm not sure about other limitation.

Google App Engine would be fine if it had suooprt for SQL database.

CloudFoundry looks interesting, but pricing is not yet defined.

I would like to avoid having to manage my environment, so Linode and EC2 are not options for me.

What are possible alternatives, and your experience with them.
