You should use the right adapter for your Repo.

Your application is still trying to use the Ecto.Adapters.Postgres adapter that was the default when you generated the app.
In your lib/app/repo.ex , change the adapter to Ecto.Adapters.MyXQL .

You can find documentation related to Ecto SQL adapters here : https://hexdocs.pm/ecto_sql/Ecto.Adapters.SQL.html
