there are two ways: 
  1. to write bash script with condition if number of conn. is > 1000 send me email and put that script in crontab
  2. monitor it with external monitoring system like zabbix, nagios etc....

s there a way to monitor active connections, or at least to report when they grow too much?
(say, I have an 8-core system and want to track down if, and when, active connections grow over 80)

You can achieve that just running simple query like
select count(*) from pg_stat_activity where state = 'active' 




Thanks, but this way I get the "sample" on that actual moment: what I'd need is to monitor, or to have something warning me like "Hey, You've got 2000 active connections! Time to grow up!" :-)

Cheers,
Moreno.-
