(3) Parallelize house keeping (for example vacuums) of the database. I
think they are going to call this processes or something slated for the
next version?
(4) Replication
(5) Referential Integritity cleanups
(6) EXOTIC FEATURES: crossdb
Oh yeah ... and we might be able to drop the whole startup time section
from the TODO list. It all depends on how one wants to implement the
threads into postgresql. Then again ... maybe a task of this endeavor
would be more appropriately forked off and proceeded on as a seperate
project (as it kinda as already been done).

The people that do the biggest amount of coding should definately code
what they feel is the best to work on - NO one is arguing that. If a few
of them want to assist in this endeavor then they should do that as well.
Most importantly - we shouldn't belittle the efforts of those that do see
the vision of how this could be beneficial in the long run. My point is
that I see more people wasting time complaining then it would take to make
up a list of coding practices to follow for future work that will make the
postgresql code base better. (Come on ... the first thing a programmer is
taught is that global variables are BAD).
