> Per-table configuration options are inherited from a hierarchy of configuration scopes. In some cases, it would be useful to denote a key as "do not inherit from the parent" (treat it as though it doesn't exist, possibly falling back on the default if the property is defined in the default configuration).
> In such cases, a property key could be prefixed with a "!" character (as in "NOT") to "unset" a key that is set with a value in a parent scope.
> This ticket removes the previously undocumented restriction that empty string is the same as a property not being set at all.
