We don't document every single optimization in the system ... if we did, the docs would be as big as the source code and equally unreadable by non-programmers. I think it's a much better idea just to mention it one place and not try to enumerate exactly which commands have the optimization. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
