Yeah. If we do this, it's is going to affect quite a few bits and
pieces that know about pg_xlog, not to mention (I think) lots of
third-party tools. So any patch doing this needs to be very carefully
reviewed before it goes into core, and on a timeline that gives
outside-of-core stuff a chance to react to it.

The biggest reason I've seen pg_xlog get deleted is not because it's
called pg_xlog, but because it's located someplace other than under
the data directory and referenced via a symlink. Renaming it might
still make it less likely for people to get trigger happy, though.
