OK, I have developed two patches.

The first fixes the problem of toast tables having oid >
FirstNormalObjectId due to recreating the information_schema as outlined
in the 9.1 release notes.  In fact, there are several cases this fixes,
but information_schema was the one reported.  The basic problem is that
TOAST tables can't be restricted by schema --  you have to gather the
relations, and then get the toast tables.  The good news is that
pg_upgrade caught its own bug and threw an error.

I was able to test this patch by testing the information_schema
recreation, and I checked to see the regression database had the
expected info.c relation count.

The second patch canonicalizes the old cluster's collation and ctype
values pulled from the template0 database.

I was recreate the fix my Debian Squeeze system.  Can someone suggestion
a way? I updated pg_database on the old 9.1 cluster to be en_US.UTF8,
while the new cluster defaults to en_US.UTF-8, but pg_upgrade kept them
the same after the setlocale() call and pg_upgrade threw a mismatch
error.
