Re: postgreSQL & amazon ec2 cloud

From the (very little) work I've done with EC2, it seems that what you get 
logically doesn't have much relation to what you get physically. I don't 
recall any guarentee that a virtual disk is equivilent to a physical 
spindle in terms of determining performance, or even that your virtual 
disk will perform consistently over time. Of course, you should test a few 
setups and see how they perform.
