Обсуждение: default_with_oid

oid's are not necessary for the table, just create the table without
oid's

oids are used by the system tables to reference each other.

ie create table foo ( id int ) without oids;

That option is only available in 7.5.  In earlier releases, you have to
create WITH OIDS or alter the table to now have oids.

There is a flag only in 7.5, which will not be released for several
months.

The column gives a unique value to each row.  Try SELECT oid FROM tab.
