A useful service, but I wonder when they will also support PostgreSQL/PostGIS?

Amazon has a good story for replication, now with RDS across availability zones, and Elastic Load Balancing, etc.

I am helping a customer with some large scale AI/text mining, and I think that they will also have me help set up a split internal data center - and AWS for overload and failover. AWS is a great deployment platform, but it does take a lot of effort to use it for projects that can't just use a platform as a service provider like Heroku.
