Yeah. Even if Make has a sane way to estimate how many jobs it should
use, I'm not sure that pg_restore does. (The most obvious heuristic
for Make is to try to find out how many CPUs there are --- but at
least it's running on the same machine it's going to be eating CPU
on. pg_restore can't assume that.)
