[...] If there's one thing I've learned in 39 years of programming it's that technical terms rarely have a fixed, universally accepted meaning. There's a reason standards include a "terms and definition" section which often define seemingly trivial terms like "byte" and why project management coaches often stress the importance of a glossary in the documentation. So I think how a single Oracle employee uses those terms has little bearing on the PostgreSQL documentation (I haven't read it yet - maybe I agree with him, but I'm also only a single PostgreSQL user). If you want to argue that the usage is wrong you would have to point at something within the PostgreSQL documentation (ideally an entry in the glossary) or some really wide-spread convention and the absence of a local definition. > Questions show many programmers are confused about the difference. Which might be a hint that no wide-spread convention on how to use those terms exists. hp -- _ | Peter J.
