As I said before, I don't like that patch: at best it's an abuse of
pqHandleSendFailure, because that function is only meant to be called
at start of a query cycle.  It wouldn't be hard to break this usage and
not notice, especially given that we often don't test back-patched
changes very carefully in the back branches if they seem OK in HEAD.

Possibly we could consider back-patching the more aggressive patch
once it's survived v12 beta testing, and just living with the issue
till then.  Given what we know now, I don't think this is a big
problem for the field: how many people use SSL on local connections?
