Data-only restores make no attempt to avoid foreign-key constraint
problems --- in general there is no solution, since you could have
circular constraints.
You could drop and re-add the FK constraints, or if you trust that the
data is valid there's the --disable-triggers option to suppress FK
constraint checking.
