If the data has moved from earlier versions (I think 7.0.x) there was a
bug in an older pg_dump that dropped a piece of information (the
related table) and the loss would be carried along. That
information is now used rather than the name passed in the args
so said dumps break on b2. Current sources should fill in the missing
information whenever possible.
