Right, I was giving that comment the side eye too.  I agree that its
second para is no longer useful: the logic it describes certainly
isn't here anymore, and there doesn't seem to be an identifiable place
where we could move it to.  (I think the concern it describes is now
baked into the table design for command tags, specifically that any
given CMDTAG either has or doesn't have a count.)  I might write the
replacement comment more like

     * If query completion data is requested and not yet filled in,
     * and the portal has a default command tag, copy it from there.
     * See QueryRewrite(), step 3, for motivation.

            regards, tom lane
