Yeah. One of the things in the back of my mind is that the planner is
going to prefer bitmap scans anyway for anything that fetches more than
a very few rows. So it's not clear that prefetching plain indexscans
is going to buy enough to justify a whole lotta work or ugliness there.
I'm content to throw this one on TODO.
