我正在尝试在运行 Amazon Linux 2023 (AL2023) 的 AWS EC2 实例中的 Postgres 15 中安装 PostGIS 扩展。但是，我之前在 Amazon Linux 2 中使用的方法不适用于新版本。基本上，AL2023 不包含额外功能，因此之前用于安装扩展的命令
amazon-linux-extras我知道AWS中的RDS包含PostGIS，但我当前的需求不需要额外的服务器，这与应用程序和数据库的单个EC2实例不同。另一方面，也许 Redhat/Centos 系列的某些存储库允许安装，但我还没有找到有关安全的信息。
作为查看可用软件包的命令的参考输出给了我

我正在开发一个项目，该项目也需要 EC2 上的 PostGIS。我找到了这个文档，但我不知道如何处理它。我们是否必须自己创建一个扩展才能使用 PostGIS？ AmzonRDS 上的 PostGIS
