This is not a VMware project, it is a TPC project. But I hear you regarding coming in from the cold and asking for a major db engine feature. I know that I have caused a lot of rolling eyes. Believe me, I have had the same (no, worse!) reaction from every one of the commercial database companies in response to similar requests over the past 25 years. No rolling of eyes from me. Clustered indexes work and if your table access mainly hits the table through that index you'll see enormous reductions in i/o. Index only scans naturally are a related optimization in the same vein. Denying that is just silly. BTW, putting postgres through a standard non trivial benchmark suite over reasonable hardware, reporting results, identifying bottlenecks, etc. is incredibly useful. Please keep it up, and don't be afraid to ask for help here.
