In fact (he said to himself), we could take this a step further and
call both the reloption and GUC "autovacuum_policy". Then we could
have two policies for this release ("always" and "never") plus allow
"default" for the reloption. Then future releases could allow users
to define additional policies, like "off-hours".

Just thinking out loud here folks...
