We're running perfsonar on a group of our servers, and while doing some maintenance work found that we
- get giant logfiles under
/var/log/postgresql
- table bloat on the database of the perfsonar scheduler
I assume the toolkit is using table locking when it does ANYTHING on the database, and always cancels the autovacuum run:

I've found several web pages talking about autovacuum tuning, but I'm wondering if it wouldn't make sense to disable autovacuum and run a vacuum analyze from a cron job.
Is there a best practice/recommendation for this kind of situation?
And maybe ask the perfsonar project to clean up their code in the long run ;}
