But how can you do that ? The oid index is only created by the dba for specific tables, thus your update would do an update with a where restriction, that is not indexed. This would be darn slow, no ? How about instead selecting the primary key and one of the tid's (I never remember which, was it ctid ?) instead, so you can validate when a row changed between the select and the update ?
