At the risk of saying something obvious and not understanding the scope of the problem, you add a column pg_amop.superclass that is a unique integer except for groups of operators like this where they can all share the same value. That's assuming you only need a transitive relationship, which seems like what you need. -- greg ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faqs/FAQ.html
