Since it still has not established that an actual problem exists in 
previous versions, this is premature. Especially as dev has not even 
reached alpha AFAIK.

To get at a solution more detailed information is needed. I would also 
suggest testing using something less the 1000 large partitions.

Information needed for any given report:

1) Postgres version being dumped from.

2) The complete pg_dump command.

3) The Postgres version being restored to.

4) The complete pg_restore command.

5) The error messages.

Also have you tried a schema only dump/restore?
