During the installation process, i was confused as to why a user came into it and what significance that user has. A brief explanation would be helpful.

Why do we need to create a user for our new database?

Difference between a user and roles. Why would we want to create a role? Do we need to worry about it?

• Quit: \q
• List users: \du
