This is just an argument for (a) using ALTER TABLE (since it will
also prevent PK indexes being created, and make it FASTer), and
(b) the ability to 'SET ALL CONSTRAINTS OFF' (or similar) to
prevent the ALTER TABLE from forcing validation of the constraint.
The current situation of creating constraint triggers is IMO not
acceptable in the long term.
There are also enough people who just restore one table to warrant
the ability for pg_dump to optionally run with constraints ON.
