A follow-up commit will teach autovacuum and manual VACUUM to fill in a TOAST table's unset storage parameters from its main table's. To be able to determine whether a parameter is set, it must default to a value that users cannot set. Of all the parameters that can be set on TOAST tables, log_autovacuum_min_duration is the only one that violates this rule. This commit changes its default to -2 so that we can tell whether it is set. This shouldn't produce any user-visible behavior changes. While at it, add assertions to ensure all storage parameters that can be set on TOAST tables continue to follow this rule.
