It's basically impossible for that to work. -j implies spawning
multiple processes that will be wanting to read concurrently from
different places in the input file. That cannot happen when the source
is a pipe. In this particular example, the pipe construct isn't even
doing anything useful; you could perfectly well write this instead:
$ pg_restore -j2 -U lfriedman -v -d nightly 2011-08-25-1314280801-nightly.out

I agree though that that's not a terribly friendly error message.
I thought we had some code in there to complain about non-seekable
input files, but it looks like we missed a case.
