Obviously, you mean exclusion constraint and not constraint exclusion
- yet another case of the bad choice of name showing up :P

(contents of the patch seem to get it right, though)

How about we call it "exclusivity constraints".

Not much of a change, but helps to differentiate.

Well, the keyword is EXCLUDE so we could call it "EXCLUDE contraints".

If that is the keyword then that is what people will use, agreed.

That is poor English, but I think we can reword the sentences to allow
