Hi,can I habe multi table indices to ensure that certain IDs can only appear in on relation?
Like table_0(id int), table_1(id int), table_2(id int) rel_1_to_0( id_1 int, id_0 int ) rel_2_to_0( id_2 int, id_0 int ) An id of table_0 should only exist either in rel_1_to_0 OR rel_2_to_0. How can I do this? regard Andreas -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
