I absolutely do. You will not convince me that whacking around the behavior of autovacuum in a maintenance release is a remotely sane thing to do. There are plenty of things wrong with the way autovacuum works today, and I am all in favor of fixing them - but not in the back-branches. Every time we whack behavior around in the back branches, no matter how innocuous it looks, somebody's environment gets broken, and then they won't apply patch releases, and it causes all sorts of headaches. At least, that's my experience at EnterpriseDB.
