 I think we need a new method on type that's specific to rendering a type
 for literal SQL.   At the moment, a string type on an encoding backend can
 pass in a bytes into render_literal_value (see
 test.sql.test_types:EnumTest.test_mock_engine_no_prob using Oracle backend
 on python3).  We're working around this by re-decoding the bytes in the
 method, but more elaborate bind processor schemes will need to be aware of
 literal SQL and naturally this should be type-based in any case.
