Sure. In many cases someone will have 3
superuser_reserved_connections and only 1 wal_sender, so it won't be
an issue. However, I still think we oughta make this (apparently
one-line) fix so that people will have the number of emergency
superuser connections that they expect to have, rather than some
smaller number that might be 0 if they have a number of SR slaves.
