Connection methods does not accept classic nor unusual arguments supported in other pgsql connection solution

还没有人认领这个 Issue。

Hello,

While trying to configure a Cockroach DB cluster async connection, there seems to be missing support for usual PostgreSQL parameters (or renamed) or supported options not frequently used.

I don't know why the connection part does not seems to follow other library but it would be nice to at least support all options existing in postgresql client (even renamed ^^).

For example, the part I am missing to connect is `options` keyword. It is used to provide complementary informations on the connection (in my case a cluster id to identify exact connection). Guess it is not mandatory by itself but it fells strange to have the issue only on asyncpg :/

* **asyncpg version**: Version: 0.26.0
* **PostgreSQL version**:
* **Do you use a PostgreSQL SaaS? If so, which? Can you reproduce
the issue with a local PostgreSQL install?**: Cockroach Cloud
* **Python version**: 3.10.7 (venv)
* **Platform**: Linux (Docker VSCode python dev container)
* **Do you use pgbouncer?**: No
* **Did you install asyncpg with pip?**: Yes (using setuptools)
* **If you built asyncpg locally, which version of Cython did you use?**:
* **Can the issue be reproduced under both asyncio and
[uvloop](https://github.com/magicstack/uvloop)?**:

报告提到了 asyncpg 的连接方法和 PostgreSQL 客户端的 options 参数，但没有指出任何仓库文件或测试。首先定位连接入口点，并将其接受的参数与 PostgreSQL 选项进行比较。在实现之前定义支持范围；完成意味着所请求的连接选项已被接受，并由回归测试覆盖。
