The second one is just to make the function work with in-place
tablespaces. Without it the function yeilds the following error.

> ERROR: could not read symbolic link "pg_tblspc/16407": Invalid argument

This looks actually odd but I think no need of back-patching because
there's no actual user of the feature is not seen in our test suite.
If we have a test that needs the feature in future, it would be enough
to back-patch it then.

So I think only the first one is needed for now.
