We support asynchronous LISTEN/NOTIFY… https://github.com/impossibl/pgjdbc-ng <https://github.com/impossibl/pgjdbc-ng>

I wasn’t sure that’s exactly what you were asking about. After connection use PGConnection.addNotificationListener to add asynchronous listeners.

May be I can call them from another thread (at least on Connection/Statement object) as the SQL is being processed, and they will return current messages, but I'm not sure when to - i.e. how do I know when a new message has been made available.
