 To support simple connection fail-over it is possible to define multiple endpoints (host and port pairs) in the connection url separated by commas. The driver will try once to connect to each of them

-## Listen/Notify
-
-> This feature not implemented yet
-
-Listen and Notify provide a simple form of signal or inter-process communication mechanism for processes accessing the same PostgreSQL database. For Listen/Notify, two actors are involved: The
-sender (notify) and the receiver (listen). The following example uses two connections to illustrate how they work together:
-
-```java
-PostgresqlConnection sender= …;
-        PostgresqlConnection receiver= …;
-
-Flux<Notification> listen = receiver.createStatement("LISTEN mymessage")
-                                .execute()
-                                .flatMap(PostgresqlResult::getRowsUpdated)
-        .thenMany(receiver.getNotifications());
-
-        Mono<Void> notify=sender.createStatement("NOTIFY mymessage, 'Hello World'")
-        .execute()
-        .flatMap(PostgresqlResult::getRowsUpdated)
-        .then();
-```                                                                                                                       
-
-Upon subscription, the first connection enters listen mode and publishes incoming `Notification`s as `Flux`. The second connection broadcasts a notification to the `mymessage` channel upon
-subscription.

 Postgres supports additional options when starting a transaction. In particular, the following options can be specified:
