I tried following the instructions in this link: Setting up PostgreSQL
I first enter:
sudo service postgresql start in the terminal after which I see * Starting PostgreSQL 9.3 database server
The next step says to type
psql to connect to the service, But when I type that into the command line, it says:
psql: FATAL: role "ubuntu" does not exist
How can I fix this? Any help is appreciated, thank you.
