Breaking Changes and Compatibility Notices

Dropped Support for PostgreSQL < 12

As of version 4.17, Hydrolix requires PostgreSQL version 12 or higher. We recommend you use PostgreSQL 13 or higher for easy upgrading. If you are using PostgreSQL version 12, enable the ltree extension as superuser, and consider upgrading to an up-to-date version of PostgreSQL.

If you're in the unlikely scenario of running the internal Hydrolix PostgreSQL pod, apply this Kubernetes configuration to upgrade PostgreSQL from version 11 to version 12 before upgrading. Also, be sure that this job runs in your cluster's namespace, not the 'default' namespace.

Upgrade on GKE:

kubectl apply -f "https://www.hydrolix.io/operator/v4.17.0/operator-resources?namespace=${HDX_KUBERNETES_NAMESPACE}&gcp-storage-sa=${GCP_STORAGE_SA}"

Upgrade on EKS:

kubectl apply -f "https://www.hydrolix.io/operator/v4.17.0/operator-resources?namespace=${HDX_KUBERNETES_NAMESPACE}&aws-storage-role=${AWS_STORAGE_ROLE}"
