> In various situations it would have been useful to me to glance at the
> operator plan before we break it into tasks and apply join, total order sort,
> etc optimizations.
> I've added this as an options to explain. "Explain physical <QUERY>" will
> output the full operator tree (not the stage plans, tasks, AST etc).
> Again, I don't think this has to even be documented for users, but might be
> useful to developers.
