libpq doesn't use either rename or unlink AFAIK. However, if we make
the patch be something involving #ifdef FRONTEND, then it will affect
other code that might want to use those.
One thing that hasn't been real clear to me is why this only affects
fe-lobj.c, when we have many other files that include <io.h> after
including postgres.h.
