I do not think this is an improvement. The places you are changing
are reacting to a connection closure. *If* we had previously gotten a
"FATAL: terminating connection due to administrator command" message,
then yeah the connection closure is expected; but if not, it isn't.
Your patch adds no check for that. (As I remarked in 2016, we could
probably condition this on the elevel being FATAL, rather than
checking for specific error messages.)
