描述

Takes a topology name and upgrades it to support large ids (int8) for topology and primitive ids. The function upgrades the following: - face (face_id column from int4 to int8, face_id_seq from int4 to int8) - node (node_id column from int4 to int8, containing_face column from int4 to int8, node_id_seq from int4 to int8) - edge_data (edge_id column from int4 to int8, edge_data_edge_id_seq from int4 to int8, left_face and right_face columns from int4 to int8, start_node and end_node columns from int4 to int8, next_left_edge and next_right_edge columns from int4 to int8) - relation (topogeo_id column from int4 to int8, element_id from int4 to int8) - topology (useslargeids column set to true)

可用性：3.6.0
