I think pg_basebackup is using homebrew code to generate tar files,
but I'm reluctant to do that for reading tar files. For generating a
file, you can always emit the newest and "best" tar format, but for
reading a file, you probably want to be prepared for older or cruftier
variants. Maybe not -- I'm not super-familiar with the tar on-disk
format. But I think there must be a reason why tar libraries exist,
and I don't want to write a new one.
