Per some discussions with a number of different people at pgconfeu, here
is a patch that changes the default mode of pg_basebackup to be
streaming the wal, as this is what most users would want -- and those
that don't want it have to make other changes as well. Doing the "most
safe" thing by default is a good idea.

The new option "-x none" is provided to turn this off and get the
previous behavior back.

I would have expected that the "stream" method would become the default.
 Just a short while ago it was proposed to remove the "fetch" method
altogether, and it was only kept because of some niche use cases.  I
don't think "fetch" is the most safe method, because it requires
wal_keep_segments to be configured.

IMO, if you are using fetch just using archive_command. Let's rip it out of pg_basebackup or at least deprecate it.
