# Answer
The error indicates a hostname resolution issue for the PostgreSQL database. This can occur due to several reasons, such as incorrect database configuration, network issues, or DNS resolution problems.
1. Check Database Configuration: Ensure that the PostgreSQL host is correctly specified in your Flyte configuration files. The hostname should be resolvable within your Kubernetes cluster.
2. Network Issues: Verify that the network policies and configurations allow communication between the Flyte components and the PostgreSQL database.
3. DNS Resolution: Ensure that the DNS service in your Kubernetes cluster is functioning correctly. You can test DNS resolution by running a DNS lookup from within a pod.
According to this discussion, re-running the Helm upgrade command with the correct values file resolved a similar issue. You might want to try updating your deployment using the correct Helm values file.
