pg_upgrade and regclass
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.

I have applied the attached patch to all relevant releases. I did a
more modest single-line code change for back branches.

Oh, I forgot to mention that this bug report came to me privately via
EntepriseDB testing.
