And then all we need is a time machine, so we can make existing
instances of pg_dump contain the tool?  It's not that easy ...

I am not sure that there's really a problem here, because I don't
think duplicate constraint names will be generated during plain
CREATE operations.  However, an ALTER TABLE might leave you with
a problem.  Hard to tell if this is critical enough to worry about.
