shp2pgsql创建一个表，但psql报告“关系...不存在”

Question

使用shp2pgsql将shapefile导入PostGIS数据库，一切正常：

Connection: host=localhost port=5432 user=aperrin dbname=tweets password='******' 
Destination: public.County_2010Census_DP1
Source File: /home/aperrin/Downloads/County_2010Census_DP1/County_2010Census_DP1
Shapefile type: Polygon
Postgis type: MULTIPOLYGON[2]
Importing shapefile (3221 records)...
Creating spatial index...

Shapefile import completed.

在psql中，\ d显示：

                          List of relations
 Schema |                  Name                   |   Type   |  Owner   
--------+-----------------------------------------+----------+----------
 public | County_2010Census_DP1                   | table    | aperrin
 public | County_2010Census_DP1_gid_seq           | sequence | aperrin

然而：

tweets=> \d County_2010Census_DP1
Did not find any relation named "County_2010Census_DP1".
tweets=> select * from County_2010Census_DP1;
ERROR:  relation "county_2010census_dp1" does not exist
LINE 1: select * from County_2010Census_DP1;

Answer 1

使用全小写表名修复了问题。使用us_counties作为表名。

Answer 2

使用大写表名称时可以使用双引号。

   select * from "County_2010Census_DP1";

Answer 3

您可能需要使用以下代码向数据库添加postgis扩展名：
