In Postgres 8.4, pg_upgrade preserved pg_class relfilenodes by creating
files in the file system. In Postgres 9.0, we changed this by creating
pg_upgrade_support functions which allow us to directly preserve
pg_class.oids.
Unfortunately, check.c was not updated to reflect this and clusters
using regclass were prevented from being upgraded by pg_upgrade.
I have developed the attached patch to allow clusters using regclass to
be upgraded. I plan to apply it to PG 9.0, 9.1, and HEAD.
