Hmm ... you manually recreated the pg_user view you say?  I wonder if
you mistakenly put it in the public schema instead of pg_catalog.
The quoted command from pg_dump is done after issuing
    set search_path = pg_catalog;
so that nothing user-created will accidentally mess it up.  If you
can still manually select from pg_user after issuing that same SET
command, then something is really seriously strange ...

If you find that indeed pg_user is in public, drop it there and
re-create it in pg_catalog.  You'll need to be superuser to do
that but I don't think it'll require any more pushups than that.
