this operator class includes comparison functions for four-byte
integers. In practice the default operator class for the field's
datatype is usually sufficient. The main point of having operator classes
is that for some datatypes, there could be more than one meaningful

either by absolute value or by real part. We could do this by defining
two operator classes for the datatype and then selecting the proper
