The reason I was speculating that was that it seems pretty unlikely
that a write() call could return ENOENT, as the above appears to
suggest.  I think that the errno = ENOENT value was not set by write(),
but is leftover from the expected failure of BasicOpenFile earlier in
XLogFileInit.  Probably write() returned some value less than BLCKSZ
but more than zero, and so did not set errno.

Offhand the only reason I can think of for a write to a disk file
to terminate after a partial transfer is a full disk.  What do you
think?
