App Platform - update DB pool without detach

Posted on February 27, 2026

I’ve created pools in my postgresql cluster. In App platform, I need to change the connection settings to point to the pool. The only option is to detach and re-attach and you can’t edit the connection directly (settings -> database -> Database/Pool). There is a drop down showing the pool/non-pool connections, but no save button.

Can this be done without downtime? I can turn on maintenance mode but it’s not ideal.

Heya, @phosphide

I believe you can create the pool in your DigitalOcean Managed PostgreSQL cluster if not already done, then manually add the pool connection string as environment variables in the App (instead of using the built-in DB attachment reference). Deploy with the new variables pointing to the pool endpoint. Once confirmed working, you can remove the old attachment.

Hope that this helps!
