postgres 函数/扩展未正确转储或恢复？

Question

更新

自我回答，请参阅此处的第一条评论和我自己的回答。

原题

我正在使用一些 sql 文件设置一个本地开发 postgres 数据库，其中一个文件创建了一个用于距离计算的自定义函数。已创建扩展 "cube" 和 "earthdistance"，函数按预期工作。

我正在转储本地开发 postgres 数据库，sql 转储包含扩展创建和自定义函数 - 看起来不错。

我正在另一台测试机器上导入转储，没有出现错误消息。

但是我在使用函数时遇到异常：

Caused by: org.postgresql.util.PSQLException: ERROR: function ll_to_earth(numeric, numeric) does not exist
  Hint: No function matches the given name and argument types. You might need to add explicit type casts.
  Where: PL/pgSQL function opengeodb_radius_selection(numeric,numeric,integer,integer) line 3 at RETURN QUERY

设置本地数据库时使用的完整SQL代码：

CREATE EXTENSION cube;
CREATE EXTENSION earthdistance;

CREATE FUNCTION
    opengeodb_radius_selection(
        baseLatitude numeric(9,6),
        baseLongitude numeric(9,6),
        radius_in_metres integer,
        opengeodb_level integer)
    RETURNS TABLE(
        locid integer,
        name character varying(255),
        distance float8)
AS
$func$
BEGIN
    RETURN QUERY
    SELECT subQueryAlias.locid, subQueryAlias.name, subQueryAlias.distance
FROM
(
    SELECT *, earth_distance(ll_to_earth(baseLatitude,baseLongitude), ll_to_earth(lat,lon)) as distance
    FROM opengeodb
    GROUP BY opengeodb.locid, opengeodb.lat, opengeodb.lon, opengeodb.name, distance
) subQueryAlias
WHERE plz is not null
AND plz <> ''
AND level = opengeodb_level
AND earth_box(ll_to_earth(lat,lon),radius_in_metres) @> ll_to_earth(baseLatitude,baseLongitude)
AND subQueryAlias.distance <= radius_in_metres
ORDER BY subQueryAlias.distance;
END
$func$ LANGUAGE plpgsql;

这是我的错还是错误的行为？

Answer 1

ll_to_earth 被定义为采用参数 (float8, float8)，但您传递的是 numeric, numeric。所以你需要在你的函数中添加一些转换。

目前还不清楚为什么它以前有效。也许您是从旧版本升级的？

Answer 2

自我回答（见第一个问题评论）

在debian系统上安装了9.4.10，debian没有9.4.10的postgresql-contrib（但在我的开发中windows postgres包，也是9.4.10）

我们已经将 debian 系统更新到 9.4.12，现在包含了 contrib，功能正常。
