As things are currently set up, a table that's uselessly using OIDs isn't going to have any serious impact on any other table. It might be worth doing ALTER SET WITHOUT OIDS just to save the microseconds required to generate an OID for each insert --- but I don't see another reason. regards, tom lane ---(end of broadcast)--- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match

As the FAQ and documentation mention, OIDs wrap around and aren't guaranteed to be unique. http://www.postgresql.org/docs/faqs.FAQ.html#item4.12 http://www.postgresql.org/docs/8.1/interactive/datatype-oid.html http://www.postgresql.org/docs/8.1/interactive/sql-createtable.html > Since we upgraded to 8.1.3, I noticed that I can create tables without an > oid column.

Avoid using OIDs; if you need a unique identifier use a serial or bigserial column. -- Michael Fuhr ---(end of broadcast)--- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly

[GENERAL] Can you run out of oids?
Somewhat silly question, but is it possible to run out of OID's?Since we upgraded to 8.1.3, I noticed that I can create tables without an oid column. I am wondering if I should consider trying to rebuild the existing tables to be built without OID. If it is possible to run out of OID's, how can you tell how close you are to the edge.Thanks,ChrisRH4.0PG8.1.3
