Re: Reference by output in : \d <table_name>

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
