I have a junction table that is recording relationships between two records in another table. Is there a way that I can create a constraint so that the values are not repeated in any order? I want to make sure that rows such as 2 and 4 in the example below cannot happen. This is a very small table that is meta data for an application. It is only 41 rows now and probably won't grow beyond 200 rows. I am on Postgresql ver 7.3.4 .
id fkey1 fkey2
1 3 4
2 10 4
3 2 7
4 4 10
5 15 8
