That doesn't seem right to me; the scenario I envision is that you are
willing to do the initial data loading over again (since you presumably
still have the source data available). But once you've got it loaded
you want full protection.
Perhaps it could work to use an ALTER TABLE command to flip the state.
But I'm not really seeing the point compared to treating it as a COPY
option. I do not believe that anyone needs this to work on individual
INSERT commands --- if you are after max speed, why aren't you using
COPY? And treating it as an ALTER property opens the possibility of
forgetting to ALTER the table back to normal behavior, which would be
a foot-gun of large caliber indeed :-(
