It seems to be a different issue. The problem with GNU tar is that it issues a warning and exits with nonzero status, which is a problem for backup scripts because they can't easily distinguish this case from an actual failure. But AFAIK the output file is self-consistent anyway. It sounds like bsd tar is just plain broken :-( regards, tom lane
