1) See

https://www.postgresql.org/docs/current/auth-peer.html

2) What OS are you on and how did you install Postgres?

3) Try

sudo -u postgres psql postgres


4) Provide the content of pg_hba.conf that starts at the line below

# TYPE  DATABASE        USER            ADDRESS                 METHOD

...
