[Bug] Failed to upgrade safeline-mgt from version 8.6.0 to 8.7.0 or 8.8.0 using Docker Compose

What happened?

While upgrading the Safeline application from version 8.6.0 to 8.7.0 or 8.8.0 via Docker Compose, the safeline-mgt service fails to start. All other services work as expected, but safeline-mgt consistently crashes during initialization.

How we reproduce?

1. Stop the running containers.
2. Pull the Docker image for safeline version 8.7.0 (or 8.8.0).
3. Run docker compose up -d.
4. Observe that safeline-mgt fails to start.

Expected behavior

All services, including safeline-mgt, should start successfully after upgrading the application version to 8.7.0 or 8.8.0 using Docker Compose.

What version is your PostgreSQL, and why doesn't it have gen_random_uuid()?

I'm using PostgreSQL 12. At first, I was confused why gen_random_uuid() wasn’t available — then I realized it’s part of the pgcrypto extension, which isn’t installed by default in this version.

Once I figured that out, I ran:
CREATE EXTENSION IF NOT EXISTS pgcrypto;

After that, everything worked as expected.
Thanks for pointing it out!
