Micro-Services: Kubernetes, Helm Charts and Docker
Pega Platform Version: 8.6.0 and 8.6.3
Ideally, While running the Install / upgrade script in the Pega Platform, If "Bypass UDF Generation" is set to "False", UDF Functions should have created however upon making the changes in setupDatabase.properties file, it did not work in our Kubernetes Environment.
Identified Blocker: PL/Java Service in PostgreSQL cluster is in Disabled state. Need to enable it and re-customize the image to support UDF Functions. But it's a risky thing of PostgreSQL Image Customization and it depends on how Devops Team Policies deined to each organization. If Custom Image deployments supported by Devops Team, It's a recomended process.
