+# Clean PostgreSQL Image
+
+**Purpose**: Build PostgreSQL from official Debian repositories to avoid compromised Docker Hub images.
+
+## Why This Exists
+
+Multiple PostgreSQL images from Docker Hub were found to be compromised with cryptocurrency miners:
+- `postgres:15-alpine` - Incident #3
+- `postgres:16-alpine` - Incident #4  
+- `postgres:14` - Incident #5
+
+This image is built from scratch using only official PostgreSQL APT repositories.
+
+## Build
+
+```bash
+cd docker/postgres-clean
+docker build -t daarion-postgres:16-clean .
+```
+
+## Verify Build
+
+```bash
+# Check no suspicious files
+docker run --rm daarion-postgres:16-clean find /tmp -type f -executable
+
+# Check process tree during startup
+docker run -d --name test-pg -e POSTGRES_PASSWORD=test daarion-postgres:16-clean
+sleep 10
+docker exec test-pg ps aux
+docker stop test-pg && docker rm test-pg
+```
+
+## Usage
+
+Replace in `docker-compose.db.yml`:
+
+```yaml
+db:
+  # image: postgres:16-alpine  # COMPROMISED
+  image: daarion-postgres:16-clean
+  # ... rest of config
+```
+
+## Security Notes
+
+- Built from Debian official repositories only
+- Minimal dependencies
+- Simplified entrypoint script (no suspicious code)
+- No hidden binaries or scripts
+- All code is readable and auditable
+
+## Maintenance
+
+To update PostgreSQL version:
+1. Edit `Dockerfile`: Update `PG_VERSION`
+2. Rebuild image
+3. Test thoroughly before deploying
