Hello, If I have a table like CREATE TABLE relationship ( obj1 INTEGER NOT NULL REFERENCES object, obj2 INTEGER NOT NULL REFERENCES object, obj3 INTEGER NOT NULL REFERENCES object, ... ) And I want to constrain that if 1,2,3 is already in the table, rows like 1,3,2 or 2,1,3 shouldn't be allowed. Is there a general solution to this problem? Sorry if the question is too basic, but I couldn't find the answer in the doc, at least not in the chapter on unique index. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
