Is there a particularly good reason for doing it that way?

In general, separate schema and data restore doesn't work in the
presence of foreign keys. (This is probably impossible for pg_dump
to handle fully, because there could be circular FK dependencies;
so it doesn't even try ATM.) Do it the easy way and use a combined
schema-plus-data dump/restore. Or if you've just got to do it that
way, drop the FK constraints, load the data, re-add the constraints.
