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

I like this patch, because I used similar functionality some years ago very successfully. The implementation is almost
simple,and the result should be valid by used method.
 

The potential problem is performance impact. Very early test show impact cca 3% worst case, but I'll try to repeat
thesetests.
 

There are some ending whitespaces and useless tabs.

The new status of this patch is: Waiting on Author
