Would it be worth replacing the condition with the equivalent?I mean would that help optimizing better some queries when it knows that a is (not) nullable or when "a" is more complicated expression?a <> a : (a IS NULL) AND NULLa = a : (a IS NOT NULL) OR NULLI think you're looking fora IS DISTINCT FROM a And that will work for cases where a might be null.I have no opinion about whether adding such a test to the planner is worth it.
