The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       not tested
Spec compliant:           not tested
Documentation:            not tested

Sorry about the prior review; I neglected to select all the appropriate buttons, leading to an errant "tested, failed" in the review.
