Right. That makes the "call count" equal to the number of times the
query is invoked.

Why should that be the definition? Partial execution of a portal
might be something that is happening at the driver level, behind the
user's back. You can't make rational calculations of, say, plan
time versus execution time if that's how "calls" is measured.
