Sounds reasonable.  Better look also at errcode_for_socket_access() and
other places that check for particular errno values.

While you are at it you might want to make sure there aren't any other
unprotected strerror() calls in the backend.  At one time we had a fair
number of places with code like

    elog("barf: %s", strerror(errno));

and I'm not sure if all of them have gotten turned into %m or not.
