Then the client has to guarantee that it can stop whatever it was doing
(which might have nothing to do with the database) every so often in
order to send a message; this isn't feasible for most clients.

The server-based method is actually no more complex to implement on the
server end and does not impose any such restrictions on the client (even
if the client sets the option and then ignores the database connection
for a long time, all that happens is that the TCP window fills up).
