The backend_start column in pg_stat_activity system view gives you the start time of the backend connection which's what you see in the ps command; however, the query_start column should give you the start time of last query within the connection. The values of these columns may not be necessarily the same if you're using connection pooling. If you don't see the data for these columns, make sure to enable the stats collection on your pg postgresql.conf file (stats_* parameters).

I checked the
pg_stat_activity table and it doesn't give any more information than I got from the ps command.
Is there any way to find out the last time the connection was used?
Thanks,
Aaron
