> 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 logical <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.
