The current version of the Redbook lists one of the April 2009 changes as "Removed the previous section 2.4 “Optimization for a complex query” to reflect APARs 74778, PK77060, and PK79236". Did you really mean "...PK74778,..."?

PK79236 says "...so that valid partitions are not erroneously disqualified." Did the deleted section show test results where valid partitions were in fact disqualified, thus invalidating the test results? Why was the whole section deleted instead of deleting or correcting just the invalid test results?

Does V9 still have the page-range scan enhancements that were described in the now deleted section?
