问题描述
我正在尝试安装postgis，并尝试将其与django集成。 我在这里关注教程。 它说以下
after connecting to db we need to add geo-extensions:
-- Enable PostGIS (includes raster)
CREATE EXTENSION postgis;
-- Enable Topology
CREATE EXTENSION postgis_topology;
-- fuzzy matching needed for Tiger
CREATE EXTENSION fuzzystrmatch;
-- Enable US Tiger Geocoder
CREATE EXTENSION postgis_tiger_geocoder;
check POSTGIS version:
postgis_lib_version();
as a tupple we add it to django settings:
POSTGIS_VERSION = (2, 1, 3)
这就是我所做的
mst=# \connect school
psql (10.5, server 10.4)
You are now connected to database "school" as user "mst".
school=# CREATE EXTENSION postgis;
CREATE EXTENSION
school=# CREATE EXTENSION postgis_topology;
CREATE EXTENSION
school=# CREATE EXTENSION fuzzystrmatch;
CREATE EXTENSION
school=# CREATE EXTENSION postgis_tiger_geocoder;
CREATE EXTENSION
school=# postgis_lib_version();
ERROR: syntax error at or near "postgis_lib_version"
LINE 1: postgis_lib_version();
关于我为什么收到此错误的任何建议。 任何我可能会丢失或做错的事情？

调用函数时，应该在它之前有一个SELECT ，否则PostgreSQL不知道如何处理该函数。
SELECT postgis_lib_version();
