Alvaro,
1. vacuum_cost_delay does not affect vacuum full
2. vacuum full is always blocking, regardless of settings
So only way is to disable other database acces if vacuum full is required.
So I gather you're not doing any vacuuming, eh?
Log files for every day are full of garbage messages below.
So I hope that vacuum is running well, isn't it ?
Andrus.
