The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           tested, passed
Documentation:            tested, passed

Oops, missed those checkboxes. Sorry for the noise. Here's correct checklist: installcheck-world passes, documented as expected. Feature is there.

Best regards, Andrey Borodin.
