Hi,

are there any disadvantages of using OID as the primary key for any
table?
What about referencing external tuples using their OIDs?

e. g.:
CREATE TABLE thistable
...
field NUMERIC REFERENCES OtherTable (oid)

Which data type should I use to reference OIDs?

Will I run into problems later if I do my things this way?

Thanks,

Markus
