Unable to start the lesson where I left off

[azakero]

Describe the bug

I completed 35% of 'Build a database of Video Game Characters' yesterday. And today when I tried to start the lesson, I am unable to login to psql with the command psql --username=freecodecamp --dbname=postgres.

Here's what I get after I run the command:

camper: /project$ psql --username=freecodecamp --dbname=postgres psql: error: could not connect to server: Connection refused Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

To Reproduce

1. Start the lesson for the first time.
2. Quit it.
3. Go to Codespaces page in Github and start it.

Expected behavior

Should connect to psql normally.
