I think it is ok to decide during creation with current settings.
When a user wants a toast table that has not been created we can direct
them to use some dummy "alter table ... set storage ..." and create a
toast
table if it does not exist (and the new settings opt for one).
And a new threshold has immediate consequences for inline compression,
so a change is not ignored.
