Thread: default_with_oid
Hello,
I’ve noticed that whenever I create a table, the DBMS is adding an OID column without my consent. I’ve also read that this behaviour can be modified (disabled) by setting the default_with_oid (to false, I suppose).
What is the OID column for? How (and where) can I find (and disable) the default_with_oid flag?
Then, a less important question for pgAdmin3 users: is it possible to manage (select / insert / update / delete) the system’s tables with this tool?
Regards,
Freddy.
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; Dave On Mon, 2004-04-26 at 11:07, Freddy Villalba Arias wrote: > Hello, > > > > I’ve noticed that whenever I create a table, the DBMS is adding an OID > column without my consent.

In earlier releases, you have to create WITH OIDS or alter the table to now have oids. > What is the OID column for? How (and where) can I find (and disable) the > default_with_oid flag? 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. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073
