This module can be used to create an Ecto Enum.

Usage:

defmodule NewType do
  use EctoEnum.Postgres, type: :new_type, enums: [:ready, :set, :go], schema: "this_is_optional"
end

Note that :type and :enums are required, while :schema is optional.

This module is meant to be used when you want to use User-defined Types in PostgreSQL.
