Thanks for this image, and the super-clear instructions!

I got `psql: error: FATAL: Peer authentication failed for user "postgres"` when running `d/boot_dev --init`.

Although the `pg_hba.conf` in `data/postgres/` had all the authentication methods set to “trust”, there was another one in `/etc/postgresql/13/main/` which had the defaults (“peer” / “md5”).

I edited `/etc/postgresql/13/main/pg_hba.conf`, changed all the methods to `trust`, did `d/shell` and ran `sv restart postgres` to pick up the changes – and was able to continue by running `d/bundle install; d/rake db:migrate RAILS_ENV=development; d/rake admin:create` manually.

Leaving here in case it’s helpful for anyone else!
