Correct. pg_receivewal only cares about the directory method, so this
thread was limited to this part. Yes, it would be nice to extend
fully the tar method of walmethods.c to support LZ4, but I was not
sure what needed to be done, and I am still not sure based on what has
just been done as of 751b8d23.

Apart from f79962d, babbbb5 and 50e1441, I don't think that there was
something left to do for this thread. Perhaps I am missing something?
