psql: Connect to the database. By default, it connects to the local socket using port 5432 with the currently logged in user.
$ psql ${database}
try on your machine
This command is used to connect to a PostgreSQL database using the psql command-line interface. The "${database}" is a placeholder for the name of the database you want to connect to. It typically needs to be replaced with the actual name of the database you want to access. For example, if you want to connect to a database called "mydb", you would replace "${database}" with "mydb" and the command would become: psql mydb Once you execute this command, psql will open a new session and prompt you to enter your PostgreSQL database username and password. Once authenticated, you can interact with the database by running SQL queries or executing other database operations through the psql interface.
