security on user for replication

We use replication with publication/subsctription. It´s ok, works fine.
But if I go to my replica server and do select * from pg_subscription
on field subconninfo I have all properties to connect. host, port, user,
password and dbname, all these info are available.
Documentation says user for replication is equivalent to a superuser and
must have the login attribute. If this user has all this power and using
that select on replica all that info is available ...
How can I hide that info from users which are connected to my replica server
or
If it´s possible to have a replication user with not superuser rights or
with NoLogin
