Actually, I think that requires two rounds of significant executor
refactoring.  This is round two:

Round one, which Tom said he was already planning to do for 9.1, is to
eliminate the hack by which "outer tuples" are passed down into
nest-loops-with-inner-indexscan.  Once those two things are done the
remaining work might be suitable for a GSoC project.
