pg_dump doesn't work well with large object ...

I have problem with pg_dump with CVS snapshot 19990526:
david=> \c test
connecting to new database: test
test=> \d
Database = test
+------------------+----------------------------------+----------+
| Owner | Relation | Type |
+------------------+----------------------------------+----------+
| david | tst | table |
| david | xinx35274 | index |
+------------------+----------------------------------+----------+

test=> select * from tst;
entry
-----
35274
(1 row)

test=> \d tst
Table = tst
+----------------------------------+----------------------------------+-------+
| Field | Type | Length|
+----------------------------------+----------------------------------+-------+
| entry | oid | 4 |
+----------------------------------+----------------------------------+-------+
EOF

But pg_dump prints:
$ pg_dump test
CREATE TABLE "tst" (
"entry" oid);
COPY "tst" FROM stdin;
35274
\.
failed sanity check, table xinv35274 was not found
===============================================================
But xinv35274 exist:

david=> \c test
connecting to new database: test
test=> select * from pg_class where relname like 'xin%';
relname |reltype|relowner|relam|relpages|reltuples|relhasindex|relisshared|relkind|relnatts|relchecks|reltriggers|relukeys|relfkeys|relrefs|relhaspkey|relhasrules|relacl
---------+-------+--------+-----+--------+---------+-----------+-----------+-------+--------+---------+-----------+--------+--------+-------+----------+-----------+------
xinv35274| 0| 501| 0| 0| 0|t |f |l | 2| 0| 0| 0| 0| 0|f |f |
xinx35274| 0| 501| 403| 2| 2048|f |f |i | 1| 0| 0| 0| 0| 0|f |f |
(2 rows)

I think, that this is problem (mainly if I need backup).
