Andres Freund 631d749007 Remove the new UPSERT command tag and use INSERT instead.
Previously, INSERT with ON CONFLICT DO UPDATE specified used a new
command tag -- UPSERT.  It was introduced out of concern that INSERT as
a command tag would be a misrepresentation for ON CONFLICT DO UPDATE, as
some affected rows may actually have been updated.

Alvaro Herrera noticed that the implementation of that new command tag
was incomplete; in subsequent discussion we concluded that having it
doesn't provide benefits that are in line with the compatibility breaks
it requires.

Catversion bump due to the removal of PlannedStmt->isUpsert.
