(Postgrex.QueryError) type _geometry can not be handled by the types module GI.PostgresTypes

I receive the following error after following the installation guide for Ecto.

[error] Postgrex.Protocol (#PID<0.1139.0>) disconnected: ** (Postgrex.QueryError) type `_geometry` can not be handled by the types module GI.PostgresTypes

Postgrex.Types.define(
  GI.PostgresTypes,
  [Geo.PostGIS.Extension] ++ Ecto.Adapters.Postgres.extensions(),
  json: Jason
)

config :gi, GI.Repo,
  types: GI.PostgresTypes

Not sure why it's trying to use _geometry, and not geometry.

Changing lib/geo_postgis/extension.ex to

  def matching(_) do
    [type: "geometry", type: "geography", type: "_geometry"]
  end

Seems to fix the error.

I had the same error. I upgraded to 3.4 and now it appears fixed?
