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. -- Michael
