Yeah, its "unlink" operation seems to be an incomplete illusion. The
fix for that is simply to reorder some cleanup operations in our error
path.

Oh, I think I just understood the root bug. It looks like a stupid
"large file" problem, 32 bit off_t being overflowed. I'll keep the
discussion off that over on the other thread. I posted a patch on
that thread; if you're able to recompile PostgreSQL, it'd be great if
you could test it. Otherwise, no worries.
