    if (conn->connhost != NULL &&
-       conn->connhost[conn->whichhost].type != CHT_HOST_ADDRESS)
+           conn->connhost[conn->whichhost].host != NULL &&
+           conn->connhost[conn->whichhost].host[0] != '\0')
        return conn->connhost[conn->whichhost].host;
-   else if (conn->pghost != NULL && conn->pghost[0] != '\0')
-       return conn->pghost;

Upon further review, the second bit of the patch is making me itching. I
think that you should not remove the second check which returns
conn->pghost if a value is found in it.
