I think you misunderstood the docs; perhaps there's an opportunity to
clarify them. The pg_dumpall run itself has to run as superuser
so that it can extract role passwords, therefore user1 has to be
superuser. What "-S" is for is to specify a superuser role name that
the dump's output script can use *at restore time* to monkey with
trigger settings. That switch exists mainly because you might be planning
to restore into a different installation with different superusers.
Therefore, that name is *not* used during the dump.
