I think your problem is here:
> PostgreSQL 8.0.3 on i386-redhat-linux-gnu, compiled by GCC
> i386-redhat-linux-gcc (GCC) 4.0.0 20050505 (Red Hat 4.0.0-4)
Recent versions are significantly smarter about grouping operations
than that dinosaur.
(Even if you must stay on 8.0.x, you should at least be running
8.0.something-recent; what you have is full of security and data-loss
risks. 8.0.24 was released this week.)
