role "nextcloud" does not exist

A question about docs/services/database.md:

When I run docker compose exec postgres psql -U nextcloud -d nextcloud, I get error: service "postgres" is not running.

When I change postgres to database-pgsql, I get error: FATAL: role "nextcloud" does not exist.

When I change -U nextcloud to -U postgres, I can connect to the database. And when I run select * from pg_user;, I get only one row with usename postgres.

Is my setup incorrect, or is it a typo in documentation?

Did you change your setup in the .env file to use postgres instead of the default mysql? The postgres container will only be used then, any users would only get created during installation of the Nextcloud container

Yes, I ran docker compose down -v, then changed the .env file, then docker compose up -d nextcloud
It looks like the service to connect to is database-pgsql, but it has no nextcloud role, only postgres.
