Is it possible to make a column case insensitive, without having to pepper your SELECTs with lots of lower() function calls (and forgetting to do it at times !)

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 operators that 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.
