--- Paths can refer to themselves, causing a tuple (N, N) in the Refs
--- table. This causes a deletion of the corresponding row in
--- ValidPaths to cause a foreign key constraint violation (due to `on
--- delete restrict' on the `reference' column). Therefore, explicitly
--- get rid of self-references.
