We just got our complimentary author hard-copies of PostGIS in Action today. Those who ordered directly from Manning should be getting there's shortly too if they haven't already. Amazon and other distributors should start shipping soon as well.
We'll be saving some copies for door prizes at the next event we present at.
I agree the postgresql.conf was something we should have spent more time on at least adding that link you mentioned in that area. Since I think that is the number one question that is asked.
The SQL Primer probably randomly ordered because at that time Leo was too tired polishing everything to be bothered with with what I wrote there. He's the grand organizer. You can probably tell which parts he wrote.
As far as maps go -- to be honest my great draw to GIS is because I always had trouble with maps and still do. I once took an aeronautics competency test and the guy giving it was baffled by my scores "According to this section you are a genius and according to this section you are a complete idiot". He might have said it in nicer terms, but needless to say I can't navigate my way out of a paper bag :).
I certainly know how hard it is to get a book that size completely polished. Thanks for the TIGER news, if I ever get around to finishing that project I talked about I may just jump right to PostGIS 2.0. It was satisfying to find the right approach to the problem I was stumped by before.
The 2ndQuadrant blog is hosted on servers at our Italian office. I know the comment part could be better. I did at least get the review published to Planet PostgreSQL, that didn't work at first this week.
