The logs show that the client's connection *was* dropped.
And on the server, the same.

We don't know the source of the problem.  I still doubt it's in postgres, but I
don't think it's helpful to blame the client, just because the client reported
the problem.  If the server were to disconnect abruptly, I'd expect the client
to report that, too.

Laurent would just have to start the conversation over (and probably collect
the same diagnostic information anyway).  The client projects could blame
postgres with as much rationale as there is for us to blame the client.

Please don't add confusion here.  I made suggestions for how to collect more
information to better understand the source of the problem, and there's
probably not much else to say without that.
