1、建线表，插入线
SET CLIENT_ENCODING TO UTF8;
SET STANDARD_CONFORMING_STRINGS TO ON;
BEGIN;
CREATE TABLE "test2" (gid serial,
"field2" varchar(254));
ALTER TABLE "test2" ADD PRIMARY KEY (gid);
SELECT AddGeometryColumn('','test2','geom','0','LINESTRING',2);
insert into test2(field2, geom)
values('Triangle', ST_GeomFromText('LINESTRING(12 23, 26 30)', 4326));
commit;
包括建表语句
2、点和线基本一致，只需要把LINESTRING改为POINT即可
3、建面表，插入面这里注意：在拼写经纬度的时候是2层括弧包住的
SET CLIENT_ENCODING TO UTF8;
SET STANDARD_CONFORMING_STRINGS TO ON;
BEGIN;
CREATE TABLE "test1" (gid serial,
"field2" varchar(254));
ALTER TABLE "test1" ADD PRIMARY KEY (gid);
SELECT AddGeometryColumn('','test1','geom','0','POLYGON',2);
insert into test1(field2, geom)
values('Triangle', ST_GeomFromText('POLYGON((10 20, 20 40, 50 15, 10 20))', 4326));
commit;
