Failed to connect to a new db under same project other than default

Hi, do you support connecting to multiple dbs under same project? it doesn't look like it at the latest version. google forestore supports multiple dbs under a same project now.

If planned to support it in future, when would that be happening? If I am wrong, please let me know.
Thanks,

Chris

**Failing test unit, Stackblitz demonstrating the problem**

Provide a failing test unit, or create a minimal, complete, and
verifiable example (http://stackoverflow.com/help/mcve) using
StackBlitz (https://stackblitz.com/edit/angular-fire-start).

**Steps to set up and reproduce**
enter a new database name into datbaseURL: Ex) databaseURL: 'https://test.firebaseio.com' (test is name of db)

**Sample data and security rules**

### Expected behavior

What is the expected behavior?
If dabaseURL is put such as databaseURL: 'https://test.firebaseio.com', it should connect to the test database.
### Actual behavior

What is the actual behavior?
it connects to default db currently.

首先追蹤 databaseURL 在目前 AngularFire/Firebase 整合中的使用方式，並確認要求的目標是 Firestore 還是 Realtime Database。使用回報的版本和非預設資料庫名稱重現該行為；完成的標準是：在不變更預設連線的情況下，與要求的資料庫之間已記錄且經過測試的連線能夠正常運作。
