For a database you want EBS as it is a virtual harddrive that
persists. Should
an EC2 instance go down, you just reattach the EBS drive on reboot.

in that situation? PG has some pretty strong requirements about
fsync
behavior etc, and I'd not want to take it on faith that a cloud
environment will meet those requirements.
Performance would be an interesting question too.

There's a place called Engine Yard offering Ruby on Rails hosting with
PostgreSQL on Amazon EC2.
Actually, we don't have any EC2 offerings for PostgreSQL yet. Well,
technically it *is* installed, but it's not pre-configured and, thus,
not supported yet.
