The OP was using the Ubuntu repo and for a given major version of Ubuntu 
that is pinned to a given major version of Postgres. I am not seeing 
changing that would go over well. Now if a user is using the PGDG repo's 
that is a different story, then you point at the repo's for the new 
Ubuntu version do an update/upgrade and you are back on track.

This is something the end user needs to work out ahead of time as there 
is an overhead in the process they need to take into consideration. 
Cranking up a new version of Ubuntu/Debian and have it take off doing 
things behind the scenes to the Postgres instance(s) would disturb me.
