Thanks for pointing that out. That might mean we can keep the
translation long-term as it won't appear in pg_settings and \dconfig,
or we might want to remove it if we want to be more deliberate about
breaking things for users who are misusing it. We maybe could just
consider that if/when all buildfarm animals are all using the new
name.
Attached updated patch.
