It's maybe not a great post, it was just one that came up when I searched.

> JDBC driver cannot receive asynchronous notifications.

Maybe their example is limited by the choice of client library.

This might be a better example? https://tapoueh.org/blog/2018/07/postgresql-listen-notify/

Or the offical postgres docs are:

https://www.postgresql.org/docs/14/sql-notify.html

https://www.postgresql.org/docs/14/sql-listen.html

https://www.postgresql.org/docs/14/libpq-notify.html

Thanks, it now makes sense.

Quite strange that this specific driver didn't support asynchronous notifications: if you have to poll the database anyway, there's no much difference between doing it without listen/notify support, I guess.
