postgresql - Azure PostgreSQL 外部数据包装器 postgres_fdw

Question

我正在尝试使用 Azure DB for PostgreSQL 实例中的 PostgreSQL 外部数据包装器 (postgres_fdw) 扩展。应支持外部数据包装器，如 Azure DB for PostgreSQL 中所述:https://learn.microsoft.com/en-us/azure/postgresql/concepts-extensions

我设法为用户创建服务器和映射，但是当我尝试导入表或架构时出现以下错误:

ERROR:  could not connect to server "<server with public hostname on AWS>"
DETAIL:  could not translate host name "<server with public hostname on AWS>" to address: Unknown host

当用公共(public) IP 替换主机名时，我得到以下信息:

ERROR:  could not connect to server "<SERVER NAME>"
DETAIL:  could not connect to server: Network is down (0x00002742/10050)
    Is the server running on host "<public IP of the server" and accepting
    TCP/IP connections on port 5432?

在 Azure DB for PostgreSQL 实例的防火墙选项中，我已经有了从 0.0.0.0 开始到 255.255.255.255 结束的AllowAllIps 规则。是否还需要配置其他内容才能访问 Azure、DNS 或防火墙配置之外的服务器？

对此并不完全确定，但前几天我们试图做类似的事情，并偶然发现了这句话(有点令人沮丧):

"Currently, outbound connections from Azure Database for PostgreSQL are not supported, except for connections to other Azure Database for PostgreSQL servers."
