You could just move the service ip address at the new postgresql master
to which the pgbouncer instances on each app server could reconnect.

I assume, with reference to https://github.com/2ndQuadrant/repmgr, that
you could use repmgrd to trigger a script to do just that at
"switchover", possibly something you would need to monitor the
"repl_events" table to achieve.
