No- peer auth allows the "postgres" unix user, which is the user that
the database runs as, to connect.

To do so, you would first "sudo su - postgres" and then run psql, and
then you'll be able to connect without any need for a password. This is
exactly what 'peer' auth is for and how it works and it's quite secure.

There's no need to ever change the authentication method to be 'trust'
and I don't recommend doing so because it's very insecure.

You don't have to restart the computer or the database when changes are
made to pg_hba.conf- you just need to issue a "reload".
