Hi,
Using of OIDs as foreign keys is recommended in the docs. It is a unique
number for every object of the PostgreSQL server. I can dump OIDs with
-o option.
But what happens if I have to upgrade my server? For example for the new
7.1 release an initdb is required. OIDs start from 16384 or something.
After importing my old databases can I expect that OIDs are not unique
any more? Or is there any other handling to prevent this?
Regards,
Oliver
