That sure sounds like the source of your problem.  It might be sane if
it killed only processes that *had been idle* for at least three
seconds, but I'm not sure there is any easy way to determine that ...
wouldn't:

select * from pg_stat_activity
where current_query = '<IDLE> in transaction'
AND query_start < current_timestamp - INTERVAL '3 seconds';

do it?
