I don't actually see the point of this. If you want dump/reload speed
you should be using COPY. If that isn't your first priority, it's
unlikely that using an option like this would be a good idea. It makes
the effects of a bad row much harder to predict, and it increases your
odds of OOM problems with wide rows substantially.
I grant that COPY might not be an option if you're trying to transfer
data to a different DBMS, but the other problems seem likely to apply
anywhere. The bad-data hazard, in particular, is probably a much larger
concern than it is for Postgres-to-Postgres transfers.
