func (*Database) RegisterNotification

func (p *Database) RegisterNotification(ctx context.Context, n database.NotificationName, f database.NotificationCallback, payload any) error

Note that this currently launches a connection+go routine to listen for notifications. It may be an idea to switch this code to only launch a single go routine for all notifications.
