Description
Since #3884 we can use postgres' listen/notify in conjunction with the JdbcMessageStore.
The current implementation is only for queues - but the listen/notify could be also used for publish/subscribe to broadcast messages to all listeners.
p.s.
I've got a working prototype for this adding an inbound- and outbound adapter.

Read issue #3884 and the existing JdbcMessageStore queue listen/notify implementation first. Then evaluate the proposed inbound and outbound adapters for publish/subscribe, using the working prototype mentioned in the issue if available; done means PostgreSQL LISTEN/NOTIFY broadcasts messages to all subscribers.
