ifthe type does not exist? 

You could wrap the lookup in a little PL/pgSQL function, something like this:

CREATE OR REPLACE FUNCTION is_valid_type(v_type text)
RETURNS boolean
AS $$
BEGIN
  PERFORM v_type::regtype;
  RETURN true;
EXCEPTION WHEN undefined_object THEN
  RETURN false;
END;
$$ LANGUAGE plpgsql stable;
