I am not totally sure why we stopped including that, but I seem to recall that we couldn't get all the mathematical notation to convert to DocBook nicely. I also misdoubt that the math wouldn't scare off the people who need it most. I agree that a little bit of basic theory might go well as a chapter in the tutorial ... but whether this is a good starting point is another question. regards, tom lane
