WHY strcmp ?! do you really think the user is a fool ?
if the user declared something "binary", he obviously knows what he has 
done.

WHY c-string ? the user only wants to get PGresult structure.
Since this structure provides a length of each value, you have no need 
in c-string. Why do think the user needs it ?

"textual-form" is just a name of actually existent convertion rule.
i am not trying to find out a philosophy here.

the actual representasion of most types is pretty useful.
