Still TBD, I think --- right now pg_upgrade would still work, but if
Vadim finishes WAL there's going to have to be a dump/reload for that.

Another certain dump/reload in the foreseeable future will come from
adding tablespace support/changing file naming conventions.

You can always stick to Postgres 6.5 :-).  There are certain features
that just cannot be added without redoing the on-disk table format.
I don't think we will ever want to promise "no more dump/reload";
if we do, it will mean that Postgres has stopped improving.
