Neither version is following the guidelines very well, in particular they
should be mentioning what kind of object %s is (file? table? tablespace?).
But to me the "could not be renamed" version seems to be closer to the
spirit of the "use complete sentences" rule for errdetail.  The other one
seems better fit for a primary error message, which is supposed to be
kept short.
