Hi,

again index access methods, can somebody shed some light into operator
classes for indexes? The documentation is an entry point, but after
reading I still don't have a clue how exactly they are used and created?
Perhaps somebody with great knowledge can supply an 101 on opeartor
classes? Because I keep getting the hint: You must specify an operator
class for the index or define a default operator class for the data type.

Greets, Yves
