Cast to (void *) rather than (int *) when passing int64's to PQfn().
This is a possibly-vain effort to silence a Coverity warning about bogus endianness dependency. The code's fine, because it takes care of endianness issues for itself, but Coverity sees an int64 being passed to an int* argument and not unreasonably suspects something's wrong. I'm not sure if putting the void* cast in the way will shut it up; but it can't hurt and seems better from a documentation standpoint anyway, since the pointer is not used as an int* in this code path. Just for a bit of additional safety, verify that the result length is 8 bytes as expected. Back-patch to 9.3 where the code in question was added.
