Bug fix for pg_upgrade from Postgres 8.3

In April, 2011, a serious pg_upgrade bug was fixed:

    http://wiki.postgresql.org/wiki/20110408pg_upgrade_fix

Unfortunately, it has been discovered that the fix did not correct
upgrades *from* Postgres 8.3.  A new fix has been committed for future
releases of Postgres branches 8.4, 9.0, and 9.1.  The details are here:

Again, this only affects users who use pg_upgrade *from* Postgres 8.3.
