I initially thought about that, but for utility statements (CTAS, etc.) being 
executed with extended query protocol, we will still not advertise the queryId 
as  we should. This is why I chose to set the queryId in PortalRunSelect and
PortalRunMulti in v2 of the patch [1].

We can advertise the queryId inside ExecutorRun instead of
PortalRunSelect as the patch does, but we will still need to advertise 
the queryId inside PortalRunMulti.
