We didn't, but while I agree with the idea, I think 5% is too low.  I
don't want autovacuum to get excessively aggressive.  Is 10% not enough?

How about the analyze scale factor, should we keep the current 10%?  I
have less of a problem with reducing it further since analyze is cheaper
than vacuum.
