Log Message: ----------- Instead of using a numberOfRequiredKeys count to distinguish required and non-required keys in a btree index scan, mark the required scankeys with private flag bits SK_BT_REQFWD and/or SK_BT_REQBKWD. This seems at least marginally clearer to me, and it eliminates a wired-into-the- data-structure assumption that required keys are consecutive. Even though that assumption will remain true for the foreseeable future, having it in there makes the code seem more complex than necessary.
