Merlin, thanks for the response. My comments below, but firstly, does
anyone know if autovacuum is affected by setting a statement_timeout?
There was a long thread here from 2007'ish:

Do you mean 6-12% of total iowait, or per cpu? Our average iowait in the
last week is 34.31% of a total 1600% with an average idle of 1451.76%. Our
iowait *does* spike occasionally (today it went up to 148.01%) but it
doesn't coincide with the lock happening. At the time of the lock we were
