How big is the dump file?  I seem to recall that tar format has a limit
on the size of individual members (tables), and maybe an overall size
limit as well.  Another issue is that I think the members are first
built as temp files in /tmp, so the member size is constrained by how
much space you have on that filesystem.

If that's the story, switching to the "custom" format is the answer.
