DBConnection Error - connection not available and request was dropped

[dimitarvp]

In config/<env>.exs (where <env> is dev, test, or prod):

config :my_app, MyApp.Repo,
  adapter: Ecto.Adapters.Postgres,
  pool_size: 10,
  migration_timestamps: [type: :utc_datetime_usec],
  migration_lock: nil,
  queue_target: 5000

Is what we had to do recently due to increased number of errors in production.
