I’m beggining with phoenix. I have a PostgreSQL database with username “postgres” and “root” as password. They are correctly modified in the config/dev.exs file.

However, when I run the “mix ecto.create” command, I have this error :

16:10:29.607 [error] GenServer #PID<0.218.0> terminating

Do you know why ? My psql credentials are correct…
