We don't need/want to hardcode a db name for postgresql activity itself, as koji db doesn't exist everywhere :)

Wondering (just another metric) selecting active, idle , others, and the three together == count() from pg_stat_activity , or just count() from pg_activity ?
select count(*) from pg_stat_activity ;
count
-------
91
select state, count(*) from pg_stat_activity where pid <> pg_backend_pid() group by 1 order by 1;
state | count
--------+-------
active | 4
idle | 93
| 5
There can be time were there is no active connections and that's fine too (so sending zero)
