postgreSQL通过postgis导入空间数据问题

通过postgis导入空间数据时出现以下问题：
Connecting: host=localhost port=5432 user=postgres password='***' dbname=costragis

"name" varchar(50));
ALTER TABLE "public"."2004shuitimian" ADD PRIMARY KEY (gid);
SELECT AddGeometryC"

咨询各位大师，什么原因
初学者，除去使用postgis导入空间数据外，还有什么方法将数据导入postgresql中呢！
