I'm looking for some up-to-date information about postgresql internals, specifically the query optimizer. I've found this link (referred to in the "Further Reading" section of the 8.4 docs):-

http://db.cs.berkeley.edu//papers/UCB-MS-zfong.pdf

but it seems quite old. That in itself is not a problem, but I wanted to be sure that I have information that is relevant. Is this the best resource for understanding how postgresql processes queries (using plans, statistics etc.) or are there others?
