But you have to ensure that your session pool is smaller than 
max_connections, since this will eat up superuser_reserved_connections and 
would make administrator intervention  impossible under certain 
circumstances.

And why do you need to hack pg_stat_activity, isn't it possible to plug 
your own view in?
