I think the fault's in your query; it's presuming a long-obsolete
convention about how idle sessions are represented in pg_stat_activity.
These days you should be filtering on "state" or "wait_event_type".
This output is just telling you that the last thing that session
did, four days ago, was a ROLLBACK.
