Agreed: there's an analogy to RAID here. When a disk goes out, it still
allows writes, but moves to a degraded state. Hopefully your monitoring
system notifies you, and you fix it.
Also, let's say that the standby suffers catastrophic storage failure.
Now you only have your data on one server anyway (the primary).
Rejecting new transactions from committing doesn't save all the old
transactions in the event of a subsequent storage failure on the
primary.
I'm not advocating this option in particular, other than saying that it
seems like a reasonable option to me.
