failed to re-find parent key

I have hacked analyze.c to automatically create a unique index on the
oid when a table is created and I am getting the failed to re-find
parent key in pg_attribute_relid_attnam_index every 8 attempts to do the
following

select * from foo into temp a;
drop table a;

Currently analyze does not create the oid index on the select into.

I realize this is beyond the realm of supported code, but can anyone
tell me what's going on or a better way to fix it.

BTW, the real problem is that select * from foo where oid=? doesn't use
an index scan.
