pg_upgrade 9.0->9.2 failure: Mismatch of relation OID in database

On upgrading a 9.0 database to 9.2 using pg_upgrade, I got this:

# pg_upgradecluster -m upgrade 9.0 main /psql/data-9.2
[...]

Mismatch of relation OID in database "hisrm": old OID 18804, new OID 18803
Failure, exiting
Error: pg_upgrade run failed

This is a cluster that was running with 9.0.12 (compiled locally). For
the upgrade, I installed postgresql-9.0 and -9.2 from
apt.postgresql.org (9.0.13, 9.2.4), so pg_upgrade was using these
versions. OS is Ubuntu 12.04 amd64 now and was 8.04 while the cluster
was still running on 9.0.12.

In the 9.0 cluster, 18804 is the relation oid of glm_lrahm_to_se.

pg_upgrade_dump_all.sql:
--
-- Name: glm_lrahm_to_se; Type: TABLE; Schema: mbs; Owner: fsv; Tablespace:

-- For binary upgrade, must preserve pg_type oid
SELECT binary_upgrade.set_next_pg_type_oid('18806'::pg_catalog.oid);

-- For binary upgrade, must preserve pg_type array oid
SELECT binary_upgrade.set_next_array_pg_type_oid('18805'::pg_catalog.oid);

-- For binary upgrade, must preserve pg_class oids

CREATE TABLE glm_lrahm_to_se (

lrahm integer NOT NULL,
se integer NOT NULL
);

UPDATE pg_catalog.pg_class
SET relfrozenxid = '14118'
WHERE oid = 'glm_lrahm_to_se'::pg_catalog.regclass;

ALTER TABLE mbs.glm_lrahm_to_se OWNER TO fsv;
