Unless your db is small, do a parallel dump. Even then, do a "-Fc" backup instead. That's been the recommended method for many years.
Ron, I've several databases, none 'large.' When I've used pg_dumpall in the past it's always with the clean option (-c) and the output directed to a specified filename with the -f option. I don't find an -F option on the man page. Anywho, specifying the 10.5 version's hostname (-h) to pg_dumpall on the 11.1 version resulted a few seconds later with an output file. Regards, Rich
