- Deliver postgres super and app passwords via mounted 0600 secret files (POSTGRES_PASSWORD_FILE, SO_POSTGRES_PASS_FILE) instead of plaintext env vars visible in docker inspect output - Mount a managed pg_hba.conf that only allows local trust and hostssl scram-sha-256 so TCP clients cannot negotiate cleartext sessions - Restrict postgres.key to 0400 and ensure owner/group 939 - Set umask 0077 on so-postgres-backup output - Validate host values in so-stats-show against [A-Za-z0-9._-] before SQL interpolation so a compromised minion cannot inject SQL via a tag value - Coerce postgres:telegraf:retention_days to int before rendering into SQL - Escape single quotes when rendering pillar values into postgresql.conf - Own postgres tooling in /usr/sbin as root:root so a container escape cannot rewrite admin scripts - Gate ES migration TLS verification on esVerifyCert (default false, matching the elastic module's existing pattern)
