With a little bit of legwork you can create an itext data type. It would 
just use textin() and textout() for the data type declaration itself. From there you'd define a bunch of comparision
operatorsthat are based 
 
on sql functions doing case insensitive comparision, plus an operator 
class and a couple of implicit casts. I don't think you'd even need a 
single line of C code for that new data type.
