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. > In fairness, the "INCLUDE" clause was added, which is new to PostgreSQL > 11, so it could raise the question as to why aren't other clauses there. 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. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
