Thread: pgsql: Provide 64-bit ftruncate() and lseek() on Windows.

Provide 64-bit ftruncate() and lseek() on Windows.

Change our ftruncate() macro to use the 64-bit variant of chsize(), and
add a new macro to redirect lseek() to _lseeki64().

Back-patch to all supported releases, in preparation for a bug fix.
