Hi,
Refering to this request http://momjian.us/mhonarc/patches_hold/msg00022.htmlI
have created a patch. The output doesn't exaclty match with what is stated here
http://momjian.us/mhonarc/patches_hold/msg00023.html.
However, it does tell the required details in a similar format.
Comments?
Thanks,
Kenneth
