By the way, I was reading the last version of the patch today, and
it seems to me that we could make the commit history if we split the
patch into two parts:
- One that introduces the new option --compression-method and
is_xlogfilename(), while reworking --compress (including documentation
- One to have LZ4 support.

v7 has been using "gzip" for the option name, but I think that it
would be more consistent to use "zlib" instead.
