Actually that would be very useful information. Questions like how is cost calculated, how are joins ordered, which kinds of subselects are pulled up to the outer query and so on are quite essential when optimizing queries and understanding query plans. Also more detailed information on how to tune the various performance parameters for bg_writer, autovacuum, checkpointing and so on would be useful in my opinion. I find the current manual very useful and the fact that it's 2000 pages doesn't make it any less useful.
