Yes, sorry, I forgot to mention that part. I have played with the
patch for a couple of hours, fixed a couple of issues, rewording and
tweaking things while browsing the whole (typedefs.list was incorrect,
docs were partially incorrect), and applied the result. I did not see
a point in 0001, as well, because the refactored "internal" function
we'd have just one caller for the proposed macro and function.

The original function pg_buffercache_numa_pages could be dropped when
upgrading to v1.7 now that the view pg_buffercache_numa relies on the
new SQL function pg_buffercache_os_pages(boolean), but I could not be
really excited about that.. We could add a DROP FUNCTION, of course.

By the way, thanks for the effort of splitting up things. This was
super useful for the review and when dealing with each part of the
proposed changes.
