postgresql book - practical or something newer?

Hey everybody. I was just informed that our organization has a credit at
amazon.com and asked if I had any books I wanted. I've been thinking
about getting a postgresql book, and from what I've seen and read
Practical PostgreSQL seems to be the standard (as well as co-authored by
Joshua Drake, somebody that has helped me many times on this very list)
but the fact that it's based on 7.x worries me. I started using
postgresql with 8.x on windows and I'm wondering if this book and it's
teachings will help me or if I should look at something targeted at 8.x
or windows. What do you guys think?
