If you think about it, NULL is not a value. It makes sens that it allows multiple NULLs. If you don't agree, than your SQL point of view doesn't match the majority, and your designs won't fit in the SQL paradigm . I think it is just a matter of experimenting, and experience to see how useful it is :) hth. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
