Funkwhale depends on Postgres for its database container. To upgrade Postgres, you need to export your database and import it into a new container to update the schema.
The following update methods are supported:

:::
### Standard upgrade
To update your Postgres container, follow these steps:
1. Create a backup of your Funkwhale database. We will import this into the new postgres container later.
```console
# docker compose exec -i postgres pg_dump -U postgres postgres > db_dump.sql
```
2. Stop all Funkwhale services
1. Stop all Funkwhale services

3. Move the {file}`data/postgres` directory to another location to back it up

### Postgres upgrade container (AMD64 only)
You can use the [`postgres-upgrade`](https://hub.docker.com/r/tianon/postgres-upgrade/) container to upgrade Postgres on **AMD64** Docker deployments. This container automates the process of upgrading between major versions of Postgres. Use these commands to upgrade your Postgres container:
1. Export your current Postgres version number. You can find this in your `docker-compose.yml` file.
```console
# export OLD_POSTGRES=13
```
2. Export the major version number you want to upgrade to.
```console
# export NEW_POSTGRES=14
```
3. Stop the Postgres container. This means no data changes while you are upgrading.
```console
# docker compose stop postgres
```
4. Run the migration using the `postgres-upgrade` container. This creates a new version of the database in the `/srv/funkwhale/data/postgres-new` directory.
```console
# docker run --rm \
-v $(pwd)/data/postgres:/var/lib/postgresql/${OLD_POSTGRES}/data \
-v $(pwd)/data/postgres-new:/var/lib/postgresql/${NEW_POSTGRES}/data \
tianon/postgres-upgrade:${OLD_POSTGRES}-to-${NEW_POSTGRES}
```
5. Re-add the access control rules required by Funkwhale.
```console
# echo "host all all all trust" | tee -a ./data/postgres-new/pg_hba.conf
```
6. Swap your old database out with your new database.
```console
# mv ./data/postgres ./data/postgres-old
# mv ./data/postgres-new ./data/postgres
```
7. Pull the new Postgres version.
```console
# docker compose pull
```
8. Restart your containers.
```console
# docker compose up -d
```

You can use the [`postgres-upgrade` container](https://hub.docker.com/r/tianon/postgres-upgrade/) to automate some of the upgrade procedure on **AMD64** Docker deployments.

That's it! Your Funkwhale pod is now running the new version of Postgres. The old database is available in `/srv/funkwhale/data/postgres-old`. You can back this up and remove it from your server once you've confirmed everything is working.
