There are some speed improvements in 8.0 too, though that wasn't the
main focus of the release cycle. For instance, Lonni Friedman's nearby
thread reports on a case where 8.0 consistently finds a much better
query plan for a complex query than prior releases did, because we fixed
some issues in the GEQO planner module.
