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 Stéphane Schildknecht
