使用JDBC catalog 时，自定义的无法应用，因为代码中是固定的。

When using the JDBC Catalog, the custom cannot be applied because it is fixed in the code.

我在做ClickHouse的JDBC catalog测试时，无法直接使用发行版的代码。

When I was testing ClickHouse's JDBC Catalog, I couldn't use the distribution's code directly.

JDBC catalog未来应该会持续拓展，所以建议采用别的方式来实例化JdbcCatalog。

The JDBC Catalog should continue to expand in the future, so it is recommended to instantiate JdbcCatalog in a different way.

稍后我会提交一个PR，希望可以采用这种方式，或者类似方式来实例化JdbcCatalog。

I will submit a PR later and hopefully instantiate JdbcCatalog this way, or something similar.
