Is it possible to use pg_backend_pid() or pg_stat_activity in some way?

I tried to put a rule on pg_stat_activity:
  create rule cleanup as on delete to pg_stat_activity do ... <cleanup code>

...but it does not work... i disconnected and the backend was removed from
pg_stat_activity, but the rule did not execute... does anybody know why??

This is an interesting idea !
But unfortunately, I think that triggers and rules are not working on system
objects.
However, I'll try it myself.

Regards !
