I'm not particularly worried about conflicting with a potential future
UPSERT command. But I do see no corresponding benefit in having a
differerent command tag, so I'm inclined to agree that ripping it out is
likely the best way forward.
On the other hand, this was noticed because Alvaro just argued that it
*should* have a new command tag. Alvaro, where do you see the advantage?
