Build fails after upstream Postgres image upgraded to Alpine 3.23

[Morl99]

The CI build for this repository fails following the upgrade of the underlying Postgres Docker image to Alpine 3.23. This change happened about 2 days ago. The error appears when installing packages with apk add, specifically a busybox trigger fails with:

execve: No such file or directory ... busybox-1.37.0-r29.trigger: exited with error 127

This did not happen with earlier Alpine versions (e.g. 3.18 or 3.19). This is likely due to incompatibilities or breaking changes related to busybox or package installation mechanisms in Alpine 3.23 under emulation/buildkit.

Workaround:
Pin the PostgreSQL Docker image to an earlier stable Alpine version (e.g., postgres:18-alpine3.18) until compatibility is restored or the Dockerfile/scripts are updated to accommodate Alpine 3.23.
