Don't I wish. Autotuning is *hard*. It took Oracle 6 years. It took
Microsoft 3-4 years, and theirs still has major issues last I checked. And
both of those DBs support less OSes than we do. I think it's going to
take more than the *right mindset* and my spare time.

Nope, just some noodling around on the configurator:

I'd be *very* interested in collaborating with you on this. Further, we
could feed DTrace (& systemtap?) into the interface to get data that
PostgreSQL doesn't currently produce.
