I was just replying the Robert that he said "But I think there must be a reason why tar libraries exist, and I don't want to write a new one." I said I am ok to use a library "what he is proposing/thinking", but explained to him that TAR is the most simpler format that why PG has its own code. > pg_dump's pg_backup_tar.c is about 1300 lines, a very large fraction > of which is boilerplate for interfacing to pg_backup_archiver's APIs. > The stuff that actually knows specifically about tar looks to be maybe > a couple hundred lines, plus there's another couple hundred lines of > (rather duplicative?) code in src/port/tar.c.
