I think changes in the system catalog should be separated from
changes in the physical on-disk structures (i.e. how tables and
indexes are stored).
Maybe I'm totally wrong, but ALTERing the pg_* tables during each
version upgrade should be relatively easy to script, when the phys-
ical on-disk structures have been solidified.
