select * from pg_stat_activity only shows the current status.

You can enable query logging, store the logs, and parse them.

select procpid, current_query, now() - query_start as duration, backend_start
from pg_stat_activity where current_query not like '%IDLE%' order by duration desc
limit 10;

Hope it may help you!!!.

Is there a way I can get a list of the top 10 longest running queries
for the day/week/month or the top 10 queries that took the most CPU?
