Rdbhost.com offers SQL databases as a web service, running Postgresql
8.3.3 .
Create a database on our server, execute queries against it in SQL via
http request, and receive results as XML or JSON. There is a python
DB API module for it as well.
The service is demand priced (you pay for actual usage), and very
modest usage levels are free.
