R-tree index operator class

The R-tree secondary-access method has an operator class defined in the sysopclasses system catalog table. This operator class, called rtree_ops, is the default operator class for the rtree secondary-access method. The database server defines the default R-tree operator class in the system catalog tables but does not provide the operator-class functions to implement this operator class.

To use an R-tree index, install a third-party DataBlade® module that implements an R-tree index. For more information about R-tree indexes, refer to R-Tree Index User's Guide.
