I'm sure this is what you meant, but you need to give them separate
*clusters*, right? Even with separate databases you can still get a list
of the other databases and other roles in the cluster. I would actually
love to be mistaken but when I looked at it a year or two ago I couldn't
find a way to lock that down (without breaking a lot of tools anyway).

Thanks!
