One of us is not understanding the other :-)  I'm asking if I have a piece of 
code that does something like select attname from pg_attribute where attrelid 
= 'stock'::regclass::oid with the intent of displaying all those attnames, 
then the "system atts" will no longer show up in that list, correct?  I'm 
asking cause I have some code that does something like this at work so 
wondering if I need to do some further investigating come Tuesday morning.
