This new release adds a new option --load-via-partition-root
to pg_dumpbinary to dump/restore data through the partitioned table only and not per partition like the default behavior. It makes the COPY statements target the root of the partitioning hierarchy rather than the partition, this may be useful when reloading data on a server where rows do not always fall into the same partitions as they did on the original server. This is the equivalent to the pg_dump option.
