@vgribok, thank you for reporting!
It might be related to #929. Someone should look into this soon and will update this issue when there is any progress.

IMO, that's unlikely. If feels more like a "copy & paste inheritance" kind of problem. I'd look for the code where default port is set, and whether the code setting Postgres Aurora cluster (regular, non-serverless) port was copied from MySQL w/o changing port constant value.
