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. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
