I've nothing against #3 as a default, but can I put in a suggestion for 1 & 3, 
or rather some setting definable at runtime/build-time that lets you select 
database + schema for autovacuum to find its config data. 

I might be wrong, but it strikes me as the sort of thing people running shared 
environments will want to choose for themselves.
