I think the OP should take a lengthier look at the whole of chapter 11
instead of looking at just one individual section within it. It's the
whole chapter that should include details about other indexing features
-- and indeed the WHERE clause is described in 11.8 Partial Indexes.
Describing every feature within the section for every other feature
would be disastrous.

IMO that's actually a bug -- the INCLUDE clause should have gotten its
own section in chapter 11 instead of being mentioned in the section
about unique indexes.
