Here's an example (log extracts) for a stats reset occurrence:
select datname, stats_reset, now()-stats_reset as since_reset
from pg_stat_database
where ( now()-stats_reset ) < interval '1 day'
order by 3 limit 1;
datname | stats_reset | since_reset

MyDB | *2024-11-21 13:48:34.332*785+00 | 00:00:22.266304
<--LOGS-->

client=[host1] app=[[unknown]]LOG: connection authorized: user=user1

What is the [2] referring to?
<.. no calls at "2024-11-21 13:48:34.332" - WHY?? ..>
My guess is the difference in time it takes to log the action and set
the log timestamp. Whereas the stats_reset value is the timestamp when
the stats system actually did the reset.

The above is some garden variety select?
