Yes, but it's *possible* that some table which would now seem to
qualify for a toast table, based on the new threshold, would not yet
have one. That would be benign; it just wouldn't be able to toast
values for that table unless you recreated it.  You can check
pg_class to find out which tables currently have toast tables.
