IMHO, not only data need to loaded before FK constraints are created but also
there has got to be a feature to allow creation of an FK constraint WITHOUT
doing the verification that all loaded/existing records satisfy the FK
constraint. The ability to create a FK constraint without verification of
existing records should exist by itself (maybe only to superuser) and also as
an option in pg_restore.
