PostgreSQL版本10是否支持pgRouting版本2.6？

Question

我通過brew安裝了pgRouting 2.6版，而我的PostgreSQL是10.4版。 現在我有一個問題：這個PostgreSQL版本是否支持pgRouting擴展？ 因為每次我查詢：

SELECT * 
FROM shortest_path('SELECT gid AS id, start_id::int4 AS source, end_id::int4 AS target, cost_length::float8 AS cost FROM network', 1, 135, false, false);

該查詢失敗並給出錯誤消息：

ERROR:  function shortest_path(unknown, integer, integer, boolean, boolean) does not exist
LINE 1: SELECT * FROM shortest_path('
                      ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

自2.0版以來，該功能已過時並從核心中刪除； 您想使用當前路由功能集合之一，例如

SELECT * 
FROM pgr_Dijkstra(
       'SELECT gid AS id,
               start_id::int4 AS source,
               end_id::int4 AS target,
               cost_length::float8 AS cost
        FROM network',
       1,
       135,
       false
     );
