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.
