We will never make such a commitment, at least not in the foreseeable
future.

I would like to see more attention paid to supporting cross-version
upgrades via pg_upgrade (or some improved version thereof) when
practical, which it should be more often than not.  But to bind
ourselves forever to the current on-disk format is sheer folly.
And if you have to convert the datafile format then you might as
well dump and reload.
