This is indeed a tricky one. I also spend a significant amount of time here. Every vendor does it differently. I looked also at programming languages such as PHP, C#. For example, C# removes duplicates. In general, having an INTERSECT on array types sounds weird. Intersection is a concept from set theory: https://en.wikipedia.org/wiki/Intersection_(set_theory) But arrays are not sets. Since we also deduplicate unions (another term from set theory), I would vote for deduplicate. -- This is an automated message from the Apache Git Service.
