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.
Is this even worth considering?
