+# Quickstart (PostgreSQL Partitioning Test)
+
+## Start Environment
+> **Note**: If `docker` commands fail with permission errors, run `newgrp docker` or ensure your user is in the `docker` group (`sudo usermod -aG docker $USER`) and log out/in.
+
+```bash
+cd postgresql/docker
+sudo ./run_test_env.sh --pg 16 --zabbix 7.0
+# Options: --pg <16|17|18> --zabbix <7.0|7.4>
+```
+
+## Verify
+```bash
+# Check status
+docker ps
+
+# SQL Shell
+docker exec -it zabbix-db-test psql -U zabbix -d zabbix
+# Password: zabbix
+```
+
+## Reset
+```bash
+docker compose down -v
+```
+
+## Partitioning
+See [PARTITIONING.md](../PARTITIONING.md) for details on the implemented declarative partitioning.
+
+## 🐳 Docker Deployment (Production)
+The `run_test_env.sh` script automatically populates `init_scripts` for the test environment. To deploy this in your own Docker setup:
+
+1.  **Mount Scripts**: Map the SQL procedures to `/docker-entrypoint-initdb.d/` in your PostgreSQL container.
+2.  **Order Matters**: Scripts execute alphabetically. Ensure they run **after** the Zabbix schema import.
+
+**Example `docker-compose.yml` snippet:**
+```yaml
+services:
+  postgres-server:
+    image: postgres:16
+    volumes:
+      # Mount Zabbix Schema first (e.g., as 01_schema.sql)
+      - ./zabbix_schema.sql:/docker-entrypoint-initdb.d/01_schema.sql
+      
+      # Mount Partitioning Procedures (Prefix to run AFTER schema)
+      - ../postgresql/procedures/00_partitions_init.sql:/docker-entrypoint-initdb.d/02_00_part_init.sql
+      - ../postgresql/procedures/01_auditlog_prep.sql:/docker-entrypoint-initdb.d/02_01_audit_prep.sql
+      - ../postgresql/procedures/02_maintenance.sql:/docker-entrypoint-initdb.d/02_02_maintenance.sql
+      - ../postgresql/procedures/03_enable_partitioning.sql:/docker-entrypoint-initdb.d/02_03_enable.sql
+      - ../postgresql/procedures/04_monitoring_view.sql:/docker-entrypoint-initdb.d/02_04_monitor.sql
+``` 
+The container will automatically execute these scripts on first startup, partitioning the tables.
