This is expected: tar format has a documented limit of 8GB per table.
(BTW, tar is not the "default" nor the recommended format, in part
because of that limitation. The custom format is preferred unless
you really *need* to manipulate the dump files with "tar" for some
reason.)

Hm, that's weird. I can't think of any explanation other than the dump
file somehow getting corrupted. Do you get sane-looking output if you
run "pg_restore -l bb.dump"?
