Spilo has, in my experience, been poorly maintained for a while. There has been some slow progress, but it doesn’t seem to be anyone’s priority right now (happy to be corrected).

I was running my own Spilo builds for a while, which was hit-and-miss. For my new (Kubernetes bare metal) cluster deployment I’ve moved over to Stackgres. I also evaluated CNPG (promising, but still early-ish days), as well as one other IIRC.

I found Stackgres to work most reliably. And it solves the biggest pain with Spilo, which is building an image with the required PG extensions. Stakgres instead has its own repository of extensions that it can install from, which is a huge help.
