"Postgres role ___ does not exist" when setting up DB 📀

[ramiAbdou]

Description

When setting up Postgres locally, developers will encounter an error:

FATAL: role "ramiabdou" does not exit

That's because our DATABASE_URL does not have a username in it, so it falls back to the OS user name. We should add the username/password to prevent needing to create any roles.

Acceptance Criteria

• Update the documentation to include creating role with password.
• All .env.example files should be updated to include the colorstack:colorstack username/password combination.
