Looking at canonicalize_path(), we have already some logic around
pending_strips to remove paths when we find a "/.." in the path, so
that's a matter of adjusting this area to trim properly the previous
directory.
On *nix platforms, we don't apply this much caution either, say a
simple /tmp/path/../path/ results in this same path used in the link
from pg_tblspc. But we are speaking about Windows here, and junction
points.
Based on the lack of complains over the years, that does not seem
really worth backpatching. Just my 2c on this point.
