+### Required Headers
+Navigate to `/system` and review the headers listed in the DEBUG section.  At a minimum, if you are using a reverse proxy the headers must match the below conditions.

+| Header      | Requirement |
+| :---        |    ----:   |
+| HTTP_HOST:mydomain.tld      | The host domain must match the url that you are using to open Tandoor.  |

+| HTTP_X_SCRIPT_NAME:/subfolder      | If you are hosting Tandoor at a subfolder instead of a subdomain this header must exist. |

+The main goal of [DockSTARTer](https://dockstarter.com/) is to make it quick and easy to get up and running with Docker.
+You may choose to rely on DockSTARTer for various changes to your Docker system or use DockSTARTer as a stepping stone and learn to do more advanced configurations.

+## PostgreSQL
+
+Postgres does not automatically upgrade database files when you change versions and requires manual intervention.
+One option is to manually [backup/restore](https://docs.tandoor.dev/system/updating/#postgresql) the database.
+
+A full list of options to upgrade a database provide in the [official PostgreSQL documentation](https://www.postgresql.org/docs/current/upgrading.html).
+
+1.  Collect information about your environment.
+  ``` bash
+  grep -E 'POSTGRES|DATABASE' ~/.docker/compose/.env
+  docker ps -a --format 'table {{.ID}}\t{{.Names}}\t{{.Image}}\t{{.Status}}' | awk 'NR == 1 || /postgres/ || /recipes/'
+  ```
+  [ ] Database Container
+  [ ] Tandoor Container
+  [ ] Database User
+2. Export the tandoor database
+    ``` bash
+    docker exec -t {{database_container}} pg_dumpall -U {{djangouser}} > ~/tandoor.sql
+    ```
+3. Stop the postgres container
+    ``` bash
+    docker stop {{database_container}} {{tandoor_container}}
+    ```
+4. Rename the tandoor volume
+    ``` bash
+    sudo mv -R ~/.docker/compose/postgres ~/.docker/compose/postgres.old
+    ```
+5. Update image tag on postgres container.
+   ``` yaml
+   db_recipes:
+     restart: always
+     image: postgres:16-alpine
+     volumes:
+       - ./postgresql:/var/lib/postgresql/data
+     env_file:
+       - ./.env
+   ```
+6. Pull and rebuild container.
+    ``` bash
+    docker-compose pull && docker-compose up -d
+    ```
+7. Import the database export
+    ``` bash
+    cat ~/tandoor.sql | sudo docker exec -i {{database_container}} psql postgres -U {{djangouser}}
+    ```
+
+If anything fails, go back to the old postgres version and data directory and try again.
+
+There are many articles and tools online that might provide a good starting point to help you upgrade [1](https://thomasbandt.com/postgres-docker-major-version-upgrade), [2](https://github.com/tianon/docker-postgres-upgrade), [3](https://github.com/vabene1111/DockerPostgresBackups).
