B-tree and hash operator classes are defined so the comparison operators of the previous section can be used with corresponding indexes.
Default B-tree operator class for temporal QUADBIN cells, ordering by the underlying temporal value.
CREATE INDEX ON trips USING btree(cells); -- uses tquadbin_btree_ops by default
Default hash operator class for temporal QUADBIN cells, used by hash joins and hash aggregation.
CREATE INDEX ON trips USING hash(cells); -- uses tquadbin_hash_ops by default
