Possible reasons why they exist: If the tables have been around since 8.0- OIDS will carry on with them. The table CREATE statements have the WITH OIDS clause. In postgresql.conf the default_with_oids setting is set on. In addition to the point I made yesterday, some old database drivers rely on OIDS to determine uniqueness. If you are positive that they are not needed you can use the ALTER TABLE table_name SET WITHOUT OIDS to remove the OID column from a table (http://www.postgresql.org/docs/9.0/interactive/sql-altertable.html) -- Adrian Klaver adrian.klaver@xxxxxxxxx -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
