Looks that way. In file.c in ~/src/bin/pg_upgrade I see:
#ifdef WIN32
300 /* implementation of pg_link_file() on Windows */
301 static int
302 win32_pghardlink(const char *src, const char *dst)
303 {
304 /*
305 * CreateHardLinkA returns zero for failure
306 * http://msdn.microsoft.com/en-us/library/aa363860(VS.85).aspx
307 */
308 if (CreateHardLinkA(dst, src, NULL) == 0)
309 {
310 _dosmaperr(GetLastError());
311 return -1;
312 }
313 else
314 return 0;
315 }
316 #endif
Great !
So I did a full upgrade for nothing (just for safety), but that's good
to know for next time !
Should this be submitted to postgresql-bugs, or is there something more
specific to the documentation ?
