Question

我有一个带postgis 2.3的postgres 9.x数据库，我创建了一个名为scuma的新模式，我跟着这个tutorial

为了使postgis函数可用于新模式但是当我尝试执行

时

SELECT AddGeometryColumn('scuma','table1','attr6',-1,'POINT',2);

我收到此错误

ERROR:  type "public.geometry" does not exist
LINE 1: SELECT public.ST_SRID('POINT EMPTY'::public.geometry)
                                         ^

PL/pgSQL function addgeometrycolumn(character varying,character varying,character varying,integer,character varying,integer,boolean) line 5 at SQL statement

我看到所有postgis函数都添加到我的新模式中，并且我已经将模式名称作为参数传递给函数，因此我不知道它为什么要查找public。这是postgis中的错误吗？如果我运行此查询，它可以工作：

SELECT AddGeometryColumn('scuma','table1','attr6',4328,'POINT',2);

更新：这是\dx

Answer 1

在该教程之后，您将所有postgis内容移动到“scuma”架构。

因此st_srid现在在scuma模式中定义，而不是在公共模式中定义。

所以你必须使用scuma.st_srid而不是public.st_srid。

请注意，您无需从“public”移动postgis函数，以便在其他模式中使用它们。

Answer 2

我相信您只是想在错误的架构中获取postgis功能。如果未在public架构中使用扩展程序，则可以将其移至scuma，如此

ALTER EXTENSION postgis SET SCHEMA scuma;

或者您可以将其保留在公共模式中，但您需要指定扩展名的位置，如上面@ fradal83所述。
