# Database administrative login by Unix domain socket Locate the line local all postgres peer as shown in the below content. $ sudo nano /etc/postgresql/12/main/pg_hba.conf To test the new password, edit the /etc/postgresql/12/main/pg_hba.conf configuration file using nano. Then, exit from the psql command-line client. To create the password, execute the statement below. When you install PostgreSQL for the first time, a password for the super-user is not set by default. This means your PostgreSQL server is ready to receive SQL commands. Once you execute the command, you will get the PostgreSQL prompt below. Under the hood, the statement above switches to the postgres UNIX USER and runs the psql command. This is the PostgreSQL server super-user or root user.įirstly, to log in to the PostgreSQL server via the psql command-line client as the postgres user, use the command below. The installation setup also creates a UNIX user named postgres. This is a command-line client that you can use to log in to the database server. You’ve successfully installed the PostgreSQL database server.īefore you begin using it, you’ll secure the root user with a password in the next step.
