Ensure default-only storage parameters for TOAST relations
to be initialized with proper values. Affected parameters are
fillfactor, analyze_threshold, and analyze_scale_factor.
Especially uninitialized fillfactor caused inefficient page usage
because we built a StdRdOptions struct in which fillfactor is zero
if any reloption is set for the toast table.
In addition, we disallow toast.autovacuum_analyze_threshold and
toast.autovacuum_analyze_scale_factor because we didn't actually
support them; they are always ignored.
