hello all
I tried recently (pgsql 7.1.2) to establish the oid of one table as foreign key
in another.
To no avail : there was no uniqueness constraint on that column
Naturally, it seems impossible to add a uniqueness constraint to such a system
column.
As far as i know, the oid is by nature unique, excepting for the case of
wrapping of their sequence.
Is there any workaround ?
