Please let's not raise that as an argument again... And not break the
s_list argument. Many users depend on that for just single sync
standbys. FWIW, I'd be in favor of backward compatibility and say that
a standby list is a priority list if we can maintain that. Upthread
agreement was to break that, I did not insist further, and won't if
that's still the feeling.
