# Självhostad Postgres för Guidad Felsökning.
# Schemat (infra/k8s/postgres-init.sql) genereras in som ConfigMap av
# kustomize och körs vid första starten — samma fil används av
# integrationstestet. För produktion rekommenderas CloudNativePG-operatorn
# (automatiska säkerhetskopior, failover, PITR).
