I don't agree with this part, mainly because there is significant number
of installations (everything that uses debian/ubuntu scripts) that
already don't have configuration files inside the data directory.

On the other matters:
+1 for renaming pg_xlog to pg_wal and pg_clog to pg_xact/trans (don't
care really which one)

And +1 for renaming pg_logical to something more reasonable.
