DETAIL: This shard has foreign constraints on it. Citus currently supports foreign key constraints only for "citus.shard_replication_factor = 1".
HINT: Please change "citus.shard_replication_factor to 1". To learn more about using foreign keys with other replication factors, please contact us at https://citusdata.com/about/contact_us.
