Isn't it also better to add notes in win32pread.c and win32pwrite.c
about the callers doing lseek(SEEK_SET) if they wish to and Windows
implementations changing file position? We can also add a TODO item
about replacing pg_ versions with pread and friends someday when
Windows fixes the issue? Having it in the commit and include/port.h is
good, but the comments in win32pread.c and win32pwrite.c make life
easier IMO. Otherwise, the patch LGTM.
