I completely agree that we document very little about EXPLAIN.  However,
I disagree that we should continue to do so.  I'd rather take the
opportunity to _add_ more details that we currently omit, and make the
documentation more complete.  A short blurb about Disabled Nodes such as
the one Laurenz proposed seems an excellent way to start; we can add
more later, as people propose them.  We don't have to stop here, and we
don't have to stay at statu quo re. other points.
