I have O'Reilly's "PostgreSQL: Up and Running, 2nd Edition" (You can buy the ebook already) and it's mostly about setting it up and administering postgres and a look at the tools around postgres. It's not a book that goes in depth on actually on how to write SQL for postgres, although it has a secton on this, or develop applications with postgres. It's more of an ops book. Anyway, I like it because coming from MySQL I was unfamiliar with how to set up and use postgres and this book set me straight.
