thx for the fast response, but I’ve put this into the common config.exs, also tried it into in dev.exs, but doesn’t help

Thx @tyoung, it’s working now, I’ve already suspected, that the issue is related to elixir 1.15 changes, but haven’t time, to sorted out.

and …, is it really the first time you post on this forum ? if so, wellcome

Haven’t tried this, but there appears to be a line missing from your config; the example under “use with Ecto” on the Felt repo has an extra types line:

#Add extensions to your repo config
config :thanks, Repo,
  database: "geo_postgrex_test",
  username: "postgres",
  password: "postgres",
  hostname: "localhost",
  adapter: Ecto.Adapters.Postgres,
  types: MyApp.PostgresTypes   # <=========== this one

Sweet serendipity, I only just got an openstreetmap data dump up and running on Monday with postgis and a Python tile server. Can’t wait to give this a spin.
