I was experimenting a bit with autovacuum now. To make the least effect possible, I started with a too high cost_delay/cost_limit-ratio. The effect of this was that autovacuum "never" finished the transactions it started with, and this was actually causing the nightly vacuum to not do it's job good enough.
