_oper_oid Oid _oper_oid[sizeof(_oper_names)/sizeof(char *)][sizeof(_type_names)/sizeof(char *)][sizeof(_type_names)/sizeof(char *)] Global 3-dimensional array that keeps the operator Oids used in MobilityDB. The first dimension corresponds to the operator class (e.g., <=), the second and third dimensions correspond, respectively, to the left and right arguments of the operator. A value 0 is stored in the cell of the array if the operator class is not defined for the left and right types.
