Authentication failed against database server at `localhost`

[tholonia]

Can you add step to your README.md?

The install did not require any psql credentials, and I can log into psql without creds as SU, but I have no idea where I am supposed to put my creds, or what they are. For people who do not know psql, don't want to know psql, or actively stay as far away as possible from psql, this seemingly small issue is a major pain to try and figure out what to do.

(crewai3) ➜  CrewAI-Visualizer git:(main) ✗ npx prisma migrate deploy
Environment variables loaded from .env
Prisma schema loaded from prisma/schema.prisma
Datasource "db": PostgreSQL database "crew_ai_visualizer", schema "public" at "localhost:5432"

Error: P1000: Authentication failed against database server at `localhost`, the provided database credentials for `postgres` are not valid.

Please make sure to provide valid database credentials for the database server at `localhost`.

Thank you for your suggestion but I have some notes about it:

• the credentials must be set here:
  DATABASE_URL="postgresql://postgres:postgres@localhost:5432/crew_ai_visualizer?schema=public"
  DATABASE_URL="postgresql://username:password@localhost:5432/db_name?schema=public"

• I think the README.md is clear and for DB configuration you can find them with some search, you just need to install the PostgreSQL and I used the default user "postgres", you just need to set its password 'postgres' as in the .env file or you can change these credentials and use the new ones in the .env.

• to contribute to the project, you need some experience in frontend, backend and DB because the project is not for beginners so you can't ignore DB configuration as a developer.
