##### Testing against PostgreSQL


By default, the tests use an in-memory sqlite database to test against. This is

the most self-contained way of testing the platform. But it is also necessary to

test against PostgreSQL. To enable the use of PostgreSQL in the tests:

1. Ensure you have an instance of PostgreSQL running locally. For example, via docker:

   ```bash

        docker run -it -p 5432:5432 --name ff-postgres -e POSTGRES_PASSWORD=secret postgres:14

   ```

2. Enable PostgreSQL mode by setting the following environment variable:

   ```bash

        export FF_TEST_DB_POSTGRES=true

   ```

   The database connection can be set using the following env vars (default values shown)

   ```bash

        export FF_TEST_DB_POSTGRES_HOST=localhost

        export FF_TEST_DB_POSTGRES_PORT=5432

        export FF_TEST_DB_POSTGRES_USER=postgres

        export FF_TEST_DB_POSTGRES_PASSWORD=secret

        export FF_TEST_DB_POSTGRES_DATABASE=flowforge_test

    ```

```

### Expected Behavior

As per MD spec, indented text should render as a code block

### Steps To Reproduce

visit and look at the section **Testing against PostgreSQL**

Look at the exports all regular (non code/monospaced) text and wrapped (no line breaks)

### Environment

_No response_
