Hi I have huge problem. Since 8.1 PostgreSQL don't make an OIDs by default. I dumped my database from v7.4 and move into v8.1. I didn't see any errors so it seems to be correct. If I tried to use database I realise that database have not OID's. Is any solution to add the OID's into this database after setting default_with_oids=true. I don't have time inserting all database again. I'm not subscribed. Please CC to me: marcin.kuk@xxxxxxxxx Marcin Kuk
