Hey folks, I’m trying to use Ecto with Neon’s hosted Postgres service. Notably, this necessitates the use of SNI to connect to the right server.

My config.exs looks like this:

import Config

config :friends, Friends.Repo,
  url: "postgres://application:nunyabidn355@ep-still-thunder-16014280.us-west-2.aws.neon.tech/friends?options=project%3Dep-still-thunder-16014280",
  # database: "friends",
  # username: "application",
  # password: "nunyabidn355",
  # hostname: "ep-still-thunder-16014280.us-west-2.aws.neon.tech",
  # port: 5432,
  ssl: true,
  ssl_opts: [
    server_name_indication: 'ep-still-thunder-16014280.us-west-2.aws.neon.tech',
    verify: :verify_none
  ]

config :friends, ecto_repos: [Friends.Repo]

mix ecto.create reports a cryptic ** (Mix) The database for Friends.Repo couldn't be created: killed and mix ecto.migrate simply reports ** (EXIT from #PID<0.99.0>) shutdown.

So, the real question I have is, how do I coerce mix into giving me some debug output so I can see what’s actually going on? In other words, I’m not interested in the answer to what’s happening here; instead I’m interested in how I might arrive at that answer myself.
