Richard,
Thank you so MUCH. I was able to delete the record by using the OID
method that you mentioned in (2).
Thanks again.

1. What type is "user_id"?
If it's a text-type, there could be unseen spaces interfering.
2. Try selecting the OID too (SELECT oid,* FROM ...) with your first
query, then use that oid in your where clause. Can you see it now? Of
course, this assumes you have oids defined for this table.
3. Have you tried re-indexing the table (REINDEX TABLE users) It's
possible the index has become corrupted while the data is fine.
