Hi,
i think we have to change the pg_dumpall "--help" message similar to pg_dump's specifying that now pg_dumpall dumps cluster into to other non-text formats.
Need similar "--help" message change in pg_restore to specify that now pg_restore supports restoring whole cluster from archive created from pg_dumpall.
