I would love to see this as an add-in project on pgFoundry. Particularly
since your online "tutorial" only works in Internet Explorer, so I can't read
it.
I believe that there was/is a team exploring a set of utilities to produce
database optimization "hints" for the admin. Your idea would dovetail
nicely with that.
