azurekeyvault support from postgres database

Is there any PostgreSQL extension called called azurekeyvault to access Azure Key Vault from the database.

```
CREATE EXTENSION azurekeyvault;
SELECT azurekeyvault.get_secret('my-secret');
azurekeyvault.set_secret('my-secret', 'my-secret-value');
```

And can we install this type of custom extensions in flexible postgreSQL managed service?

Thanks,
Rinshad.
