Question

我正在尝试在pgAdmin 4中执行此查询，但是每次尝试运行它时都会遇到错误。请参阅下面的代码和错误：

SET statement_timeout = 0;
SET client_encoding = 'UTF8';
SET standard_conforming_strings = off;
SET check_function_bodies = false;
SET client_min_messages = warning;
SET escape_string_warning = off;

一些背景知识：我有以下扩展名

pgrouting
PLPGSQL
PostGIS的
postgis_topology
fuzzystrmatch

在x86_64上运行PostgreSQL 10.3版本

我收到以下输出消息：

ERROR:  function st_ndims(public.geometry) does not exist
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.
SQL state: 42883

我在这里出错的任何想法？原始函数是CONSTRAINT enforce_dims_the_geom CHECK ((public.ndims(the_geom) = 2)),但是当阅读这个PostgreSQL 10.3时，不再支持ndims并且现在已经切换到st_ndims。但是当我改变它时，它仍然没有被识别。

Answer 1

问题是您已从搜索路径中删除了public，因此找不到此架构中的任何内容。

尝试

SET search_path = public, routing, pg_catalog;

Answer 2

感谢小费。我遇到了这个问题，因为带有-a扩展名的 pg_dump 默认情况下会添加以下语句，从而删除search_path

SET statement_timeout = 0;
SET lock_timeout = 0;
SET idle_in_transaction_session_timeout = 0;
SET client_encoding = 'UTF8';
SET standard_conforming_strings = on;    
SELECT pg_catalog.set_config('search_path', '', false);
SET check_function_bodies = false;
SET xmloption = content;
SET client_min_messages = warning;
SET row_security = off;

我必须禁用它才能添加数据

使用posgis的PostgreSQL查询
