Thread: pg_dump without oids

Hi all,

pg_dump and pg_dumpall have the -o option that should tell them to
include oids in dump. I didn't chose this option, and the dump doesn't
include "WITH OIDS", but the tables are created with oids when restoring
this dump.

I'm dumping from 7.4.5 to 8.2.1.
I do have
#default_with_oids = off
in postgresql.conf for 8.2.

Is there a way to prevent creating table with oids ?

A table created by psql client is created without OID.

Thanks by advance

You misunderstand what that option is for: it's for trying to preserve
the exact OID values present in your old installation.  It's not about
adding or removing OID columns.

No, and I don't think it'd be within pg_dump's charter to editorialize
on table definitions like that.  Instead see ALTER TABLE SET WITHOUT OIDS.
