Hehe. I have one I am setting up that will be dedicated to postgresql,
hence my question about a week ago about disk partitioning/striping :-)

The database is for weather data from multiple sources. When adding a
new dataset, I have to create/test/delete/recreate the config in the
FKed table. Users don't have this power, but I need it.
Drop/delete/recreate is a totally acceptable solution for this scenario.
I guess I was wondering if there is other general tuning advice for such
large table indexes such as increasing statistics, etc.
Thanks,
