No idea.  My change only enables access to large files, it doesn't change
the segmentation logic in the backend.  The main use at this point is for
pg_dump-related activities.

In fact, while the large file support API can handle 64-bit offsets, its
availability and use don't guarantee that the file system will support any
particular file size.  So the segmentation logic in the backend isn't
going anywhere, as far as I'm concerned.
