So the assumption is that you'd actually *do* the query, then report
back the plan tree plus measured statistics? Interesting thought.
But how will you separate time for parent and child plan nodes?
AFAICS, every plan node will show essentially the same elapsed time
from start to finish, if you are going to just record wall-clock time
at node startup and shutdown.
