如何在Quarkus中使用反应式数据源选择Postgres模式

<dependency>
    <groupId>io.quarkus</groupId>

</dependency>

quarkus.datasource.url=jdbc:postgresql://localhost:5432/mydatabase
quarkus.datasource.driver=org.postgresql.Driver
quarkus.datasource.username=myusername
quarkus.datasource.password=mypassword

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    private String email;

    // 省略构造函数、getter和setter方法
}

import io.quarkus.hibernate.reactive.panache.PanacheRepository;

public interface UserRepository extends PanacheRepository<User> {
}

import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;
import javax.transaction.Transactional;

import io.smallrye.mutiny.Uni;

@ApplicationScoped
public class UserService {
    @Inject
    UserRepository userRepository;

    @Transactional
    public Uni<User> createUser(User user) {
        return userRepository.persist(user)
                .onItem().transformToUni(savedUser -> Uni.createFrom().item(savedUser));
    }

    @Transactional
    public Uni<User> getUserById(Long id) {
        return userRepository.findById(id);
    }

    @Transactional
    public Uni<Void> deleteUser(Long id) {
        return userRepository.deleteById(id);
    }
}
