FWIW, I don't really see why it would be bad to have 0 mean that
"there's no query ID for some reason" without caring whether that's
because the current statement is a utility statement or because
there's no statement in progress at all or whatever else. The user
probably doesn't need our help to distinguish between "no statement"
and "utility statement", right?
