I kind of like Alvaro's wording because it helps to reinforce the point
that pkeys are a type of unique constraint. If you dislike repeating
"constraints", perhaps we could go with something like
Unique constraints (and hence primary keys) on partitioned tables ...
I'm not hugely against your wording though.
