After a lot of distractions, I've finished applying the planner fixes
that seem necessary in view of your report about poorer planning in 8.4
than 8.3.  When you have a chance, it would be useful to do a thorough
test of CVS HEAD on your data and query mix --- are there any other
places where we have regressed relative to 8.3?
