A couple of pg_dump questions

$ pg_dump --host=farawaysrvr -Fc $REMOTEDB > /local/disk/backups/$REMOTEDB.dump

Is the data compressed on the remote server (thus minimizing traffic on the 
wire), or locally?  (I'd test this myself, but the company has really strict 
firewall rules in place.)

$ pg_dump --host=farawaysrvr -Fc -j4 $REMOTEDB > 
/local/disk/backups/$REMOTEDB.dump

Will parallel backups work if pg_dump is v9.6 and the remote system is v8.4?

Thanks
