As as experiment, I've created two Aurora databases, one serverless and one not, to test whether or not outbound connections are possible with Aurora Serverless. Both databases are in identical subnet groups with identical security groups.

The serverless instance returns this error message:

DETAIL:  could not connect to server: Connection timed out
Is the server running on host "xxxx" (xxxx) and accepting
TCP/IP connections on port 5432?

The "regular" instance created a foreign schema and imported the requested tables as expected.Is there a setting or parameter that I need to adjust, or is this functionality not supported due to the architecture that enables this particular offering?

是的，您可以通过在 Aurora Serverless 上运行以下查询来检查这一点：

show rds.extensions;

列表中会有一些，并且postgres_fdw是其中之一。
