Here's my WIP series addressing this and related problems. With this
we're again noticeably faster than the dynahash implementation, in both
the case here, and the query you brought up over IM.
This definitely needs some more TLC, but the general approach seems
good. I particularly like that it apparently allows us to increase the
default fillfactor without much downside according to my measurements.
