Well, on closer look, there it is in plain sight in the runtime config
documentation I've looked through a hundred times for other purposes. Just
one of many features I haven't discovered, I guess.

The 7.3.4 doc (doc/html/runtime-config.html) does say the log_connections
option can only be set at server start or in the postgresql.conf
configuration file. That seems a little ambiguous on the SIGHUP'ability of
that option. My 7.3.4 install here shows all the log_* options are
dynamically reloadable.
