How to resolve? Quotation from http://www.postgresql.org/docs/current/interactive/ddl-inherit.html : A serious limitation of the inheritance feature is that indexes (including unique constraints) and foreign key constraints only apply to single tables, not to their inheritance children. This is true on both the referencing and referenced sides of a foreign key constraint.
