The obvious solution would be to create a UNIQUE index on everything except the primary key - 'id' - but that's a 10-column index and doesn't sound very efficient. Am I missing something more obvious? gvim -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
