I have defined various operators for some user defined types. How do
I use them for setting up an index on the types?
The naive approach yields the following
ERROR: DefineIndex: type geocentric_point has no default operator class
so presumably one must define a default operator. How is this done
and what exactly are the semantics of a default operator?
Thanks for your help.
Cheers,
Brook
