Uh, yes, but you can't turn them off. I suspect I don't understand
your question. Do you mean the "runtime statistics" section of the
configuration file? If that's what you mean, then no. Those aren't
the same thing as the statistical data used by the planner; the
latter is updated when you run "analyse".
