The plot thickens...
I noticed that I have similar queries that work as expected. The difference
appears to be that every query that is broken uses " WITH ROLLUP", and removing
this makes them behave as expected.
Is this a known bug? Should I submit it as such?
If someone would be so kind as to point me to the bug system, I'll crawl around
in there to see if it's a known problem.

:::: The competition for grain between the wealthy car drivers of the world and
the poorest people who are trying to survive is a moral issue that we should
not ignore. The continued increase in biofuels production will result in a
continued decrease in food availability, which we could someday consider to be
a crime against humanity. -- Pat Murphy
