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 ?
