Hello.

It is necessary to restart PostgreSQL to bind to a different network
interface, thus breaking the active connections. This patch draft
makes it no longer necessary, just assign the new value to
`listen_addresses` GUC and send SIGHUP to Postmaster.

Do you think it is useful? Is there any chance to push it upstream?
Overall thoughts?
