Thinking about this some more, there's the case of somebody accidentally
using an already existing slot that was meant for another standby which
happens to be down just at that moment.
From some quick testing, that makes replication fail once the other
standby is started up again, but soon after the new standby is taken
down, replication picks up without apparent problems for the other
standby.
