But there can be a valid second question - it can be nice to use extensions with availability to define their own communication protocol. Postgres has a special protocol for replication or for backup. With this possibility you can do what you need without the necessity of an external application server.

And here we are back on the Babelfish question. Babelfish defines its own protocol (TDS = Table Data Streaming) but it requires building PostgreSQL from the source, with some hooks for the additional protocol. A built in mechanism to do that without rebuilding would be nice. Babelfish Postgres is version 13.5, currently the most prevalent version in the data centers. A library to implement foreign communication protocol primitives would be a very nice thing indeed.
