Is it feasible to make a utility to rewrite each table, shortening the headers and making any other necessary changes? (Taking for granted that the database has been vacuumed and the postmaster shut down.) This could build up over successive releases, with an input section appropriate to each older version and an output section for the current version. Then an upgrade from any older version to the current one could be done by pg_upgrade.
