I don't think this is a question of "right" vs. "wrong". You are certainly
entitled to your opinion, but I believe that I am entitled to mine, too.

Well, as far as I know, it's up to me which parts of your emails I want to
quote in my reply. I did read this part. It did not change my opinion. My
fundamental objection to your proposal is that I think it is too wordy. I
think users will generally know whether they are using partitioning or
inheritance, and if they don't it's not hard to figure out. I don't think
quoting only part of what you wrote made the quote misleading, but it did
allow me to express my opinion. I understand that you don't agree, which is
fine, but I stand by my position.
