Many thanks
I think the problem with using the oid from the primary table is that may
rows in the view definition will get the same oid because of the union.
Thanks very much anyway.
I will look at the temporary sequence although I am not sure if sequences
work with views.

You can get an oid from some table in view definition. May be it
results to resolve your problem...
You can also try "create temp sequence" (review
