Delete oid causing problems

Hi all,
I am trying to delete a record which had one of the fields as oid.
I was able to delete all the records except for 3.
I tried:
select lo_unlink(64445) from tablename
And then:
delete from tablename where id=1;

it worked
But for 3 records the delete command goes in hang.

on executing:
select lo_unlink(67787) from tablename

it gives:
lo_unlink
-----------
-1
-1
(2 rows)
and on deleting with the delete command it goes on hang.

I want to drop the same table but can't do that either.
I want to create another table with the same name.

Any help would be appreciated.

Thanks in advance,
Rai
