Right. Our code was nearly entirely broken for streaming replication for
*years* without anybody noticing. And even now it doesn't reliably
work. It's also pretty hard to test due to the required data volumes and
the vast number of different behaviours across openssl versions.

Yes, I think so. Maybe log a warning at startup if set to nonzero
(startup is probably the best we can do).
