稍后，对于您的产品级别的应用程序，您可能会要使用像**PostgreSQL**这样的数据库服务器。

这儿有一个**FastAPI**和**PostgreSQL**的官方项目生成器，全部基于**Docker**，包括前端和更多工具：<a href="https://github.com/tiangolo/full-stack-fastapi-postgresql" class="external-link" target="_blank">https://github.com/tiangolo/full-stack-fastapi-postgresql</a>

请注意，大部分代码是`SQLAlchemy`的标准代码，您可以用于任何框架。FastAPI特定的代码和往常一样少。
