Update our documentation concerning where to create data directories.
Although initdb has long discouraged use of a filesystem mount-point
directory as a PG data directory, this point was covered nowhere in the
user-facing documentation. Also, with the popularity of pg_upgrade,
we really need to recommend that the PG user own not only the data
directory but its parent directory too. (Without a writable parent
directory, operations such as "mv data data.old" fail immediately.
pg_upgrade itself doesn't do that, but wrapper scripts for it often do.)
Hence, adjust the "Creating a Database Cluster" section to address
these points. I also took the liberty of wordsmithing the discussion
of NFS a bit.
These considerations aren't by any means new, so back-patch to all
supported branches.
