Currently, we just work around the problem by running VACUUM FULL on

I tried to make the updates to the table much less frequent (storing
recalculated priorities happens every 5 minutes, instead of every few
seconds), so the problem should be reduced.
As I mentioned before, you can avoid having to run vacuum full by running
normal vacuums much more often.
