First I wanted to verify that pg's IO rates were inferior to The Competition.
Now there's at least an indication that someone else has solved similar
problems. Existence proofs make some things easier ;-)
Is there any detailed programmer level architectual doc set for pg? I know
"the best doc is the code", but the code in isolation is often the Slow Path to
understanding with systems as complex as a DBMS IO layer.

The source is freely available for your perusal. Please feel free to
point us in specific directions in the code where you may see some
benefit. I am positive all of us that can, would put resources into
fixing the issue had we a specific direction to attack.
