Your pg_stat_activity output shows the backend is idle, meaning it's
waiting for a client command.  While the session has been around for
days, we can see the last client command was about 47 minutes ago,
from your "now() - pg_stat_activity.query_start AS duration" column.
I see no reason to think there is anything interesting here at all,
except for a client that is sitting doing nothing for long periods.
