In older versions of postgresql that would scan the whole table. In 8.1
and above it doesn't. However, I am guess that since this is a
partitioned table the planner isn't smart enough to just perform the
query on each child and a max on the set that is returned.
It is not. Feel free to submit a patch for planagg.c ...
I think my patch to pgbench may have set your expectations of me a bit
high ;)...
