Sounds horribly confusing.  It's not very difficult to write a script
to set this value for every table in the database, if that's what you
want to do.  Having autovacuum_enabled potentially mean two different
things depending on the value of some GUC sounds like a recipe for
confusion (and no I don't like it any better if we put the global
switch somewhere other than a GUC).
