a table was created with:

create table bills (id        serial    not null,account_no     int4    not null,date_issued    date    not null,.....
);

The following SQL script returns only 1 row of data:
select oid, * from bills where id = xxxxx' order by oid;



However with the following SQL:
select oid, * from bills where date_issued = '01/01/2001' order by oid;

some of the data is duplicated, including the OID.

When trying to 'vaccum' the database, get

NOTICE:  Index bills_id_key: number of index tupples (4755) is not the
same as heap (7800).

What is happening? What could have caused this?

Database version used is V6.50. I know it's old, but i hope it's not the
version that's causing this problem.

Thanks in advance for any suggestions.
