**Apache Airflow version**: 2.0.2
**Kubernetes version (if you are using kubernetes)** (use `kubectl version`):
1.17.9
**Environment**:
- **Cloud provider or hardware configuration**: azure
- **OS** (e.g. from /etc/os-release):
- **Kernel** (e.g. `uname -a`):
- **Install tools**:
- **Others**:
**What happened**:
When starting a pod, the error message says
```
/entrypoint: line 109: BACKEND: unbound variable
```
We use an azure-hosted postgres database for the backend, which MUST contain a @ in the username for it to work. The previous versions of airflow handled this just fine. But since the changes in this ticket: https://github.com/apache/airflow/issues/14104 it no longer works because the regex has been changed and now does not accept a @ character in the username.
<!-- (please include exact error messages if you can) -->
**What you expected to happen**:
I expect it to accept a @ in the username
<!-- What do you think went wrong? -->
**How to reproduce it**:
Start airflow with a connection string like this:
```
postgresql://airflow@env:password@env.postgres.database.azure.com:5432/airflow
```

As minimally and precisely as possible. Keep in mind we do not have access to your cluster or dags.

For details /specification see here: https://tools.ietf.org/html/rfc3986
* '@' is part of gen-delims (type of reserved characters)
* Userinfo is defined like this: `userinfo = *( unreserved / pct-encoded / sub-delims / ":" )` - which means that gen-delims cannot be used, they must b pct-encoded

Using @ in user name is not allowed by specification see for example here: https://stackoverflow.com/questions/10050877/url-username-with . If the user contains @ you MUST percent-encode it (replace with `%40`)
