COMMERROR exists to keep us from trying to send an error report down a
failed socket. I would assume (perhaps wrongly) that
walsender/walreceiver don't try to push error reports across the socket
anyway, only to the postmaster log. If correct, there is no need for
COMMERROR, and using it just muddies the code.
