That's not bogus, it's the intended behavior.  Per the source code:

     * If we are escaping a literal that contains backslashes, we use the
     * escape string syntax so that the result is correct under either value
     * of standard_conforming_strings.  We also emit a leading space in this
     * case, to guard against the possibility that the result might be
     * interpolated immediately following an identifier.
