Bad error message for postgres-level erro

Version: 0.10.0

Managed to get a not very helpful error message when inserting a string that was too long for the VARCHAR(255) column it was supposed to be inserted into:

** (exit) exited in: :gen_server.call(#PID<0.213.0>, {:query, #Reference<0.0.1.2581>, 15000}, 5000)
    ** (EXIT) no process

Code that generated it (content was coming from 3rd party web app):

defmodule Mix.Tasks.FetchAllVideos do
  use Mix.Task
  def run(_) do
    Day9tv.Repo.start_link
    {:ok, items, next_page_token} = Day9tv.YouTube.playlist_items("UUaxar6TBM-94_ezoS00fLkA")
    Enum.each items, fn(item) ->
      changeset = Day9tv.Video.create_from_youtube(item)
      Day9tv.Repo.insert!(changeset)
    end
  end
end

This looks like pooling issue in ecto. See my comment there.
