What feature would you like to see?

Hi Kubeflow team and community,

I’ve been following this issue closely since our company, due to internal policies, cannot use MySQL, and we’re really looking forward to full PostgreSQL support in Kubeflow Pipelines. The flexibility of PostgreSQL would be a major advantage for us in deploying and managing our ML workflows.

Could the maintainers provide an update on the timeline or roadmap for officially supporting PostgreSQL? We’d love to know when we might expect this integration to be fully implemented.

Thanks for all the great work on this project!

Best regards
