Create an outdated database:
```bash
mkdir test-db
docker run --rm --name testdb -u 1000 -e POSTGRES_PASSWORD=password -v $(pwd)/test-db:/var/lib/postgresql/data -it postgres:16
docker run --rm --name testdb --env PGDATA=/var/lib/postgresql/data -u 1000 -e POSTGRES_PASSWORD=password -v $(pwd)/test-db:/var/lib/postgresql/data -it postgres:17
```
Perform the migration (you need to replace `POSTGRES_USER` and `POSTGRES_PASSWORD` with the credentials of the root user of the database):
```bash
docker run -u 1000 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=password -v $(pwd)/test-db:/db --rm -it pierre42100/postgresmig:16to17
docker run -u 1000 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=password -v $(pwd)/test-db:/db --rm -it pierre42100/postgresmig:17to18
