Re: Altering existing table to be WITHOUT OIDs

For the benefit for anyone who may search this list in the future for this
information, I used the following queries to implement Tom's suggestion on
the table "list_entries" in this example:

UPDATE pg_class SET relhasoids=false WHERE relname='list_entries';
DELETE FROM pg_attribute
     WHERE attrelid = (SELECT oid FROM pg_class WHERE relname =
'list_entries')
         AND attname='oid';

You might want to also include the reltype in the sub-SELECT if you re-use
names willy-nilly.

Cheers,

Doug
