Will Index-only-scan be in 9.2

I was wondering if the index-only-scan will be available in 9.2? This is not having to visit the real data to answer a
query,if all the information is available in the index. I think this will be a mayor step in overtaking the big O in
theg-spot.
 

There seams to already be some patch for this problem, but I don't know if you are considering this for the next
release?Why is the enthusiasm so low on this feature? I would presume this is a mayor performance boost, not having to
runthrough millons of stupid pages if all the info is already in the index.
