Hello, My first impression is that vacuuming the offending table very often helps a lot. I'm doing it by hand for now but I will have a cronjob for this. By the way, it seems I don't need thoses indexes anymore. Thanks a lot for your helpful advices.
Excellent! Oh, when you set up your cron-job, it's probably better to vacuum this sort of table too often rather than not enough.
