Question

我正在使用geoDjango。我已从源Gdal，proj1.4，geos3.3.5和Postgis2.0.1安装了以下软件包。我是ubuntu用户。当我在此之后运行syncdb时，我遇到了以下错误。我错过了什么吗？感谢

Answer 1

也许我有点迟了但我解决了这个问题（Django 1.4.x，Postgis 2.0.1和PostgreSQL 9.2）在template_postgis数据库中创建一个运算符类，如下所示：

CREATE OPERATOR CLASS gist_geometry_ops
FOR TYPE geometry USING GIST AS
STORAGE box2df,
OPERATOR        1        <<  ,
OPERATOR        2        &<  ,
OPERATOR        3        &&  ,
OPERATOR        4        &>  ,
OPERATOR        5        >>  ,
OPERATOR        6        ~=  ,
OPERATOR        7        ~   ,
OPERATOR        8        @   ,
OPERATOR        9        &<| ,
OPERATOR        10       <<| ,
OPERATOR        11       |>> ,
OPERATOR        12       |&> ,

OPERATOR        13       <-> FOR ORDER BY pg_catalog.float_ops,
OPERATOR        14       <#> FOR ORDER BY pg_catalog.float_ops,
FUNCTION        8        geometry_gist_distance_2d (internal, geometry, int4),

FUNCTION        1        geometry_gist_consistent_2d (internal, geometry, int4),
FUNCTION        2        geometry_gist_union_2d (bytea, internal),
FUNCTION        3        geometry_gist_compress_2d (internal),
FUNCTION        4        geometry_gist_decompress_2d (internal),
FUNCTION        5        geometry_gist_penalty_2d (internal, internal, internal),
FUNCTION        6        geometry_gist_picksplit_2d (internal, internal),
FUNCTION        7        geometry_gist_same_2d (geom1 geometry, geom2 geometry, internal);

你需要创建一个postgis模板并加载相关的postgis.sql

说你的postgis路径是/usr/share/postgresql/8.4/contrib 运行这个


POSTGIS_SQL_PATH=/usr/share/postgresql/8.4/contrib
sudo -u postgres createdb  -E UTF8 template_postgis1 # Create the template spatial database.
sudo -u postgres createlang  -d template_postgis1 plpgsql # Adding PLPGSQL language support.
sudo -u postgres psql  -d postgres -c "UPDATE pg_database SET datistemplate='true' WHERE datname='template_postgis1';"
sudo -u postgres psql  -d template_postgis1 -f $POSTGIS_SQL_PATH/postgis.sql # Loading the PostGIS SQL routines
sudo -u postgres psql  -d template_postgis1 -f $POSTGIS_SQL_PATH/spatial_ref_sys.sql
sudo -u postgres psql  -d template_postgis1 -c "GRANT ALL ON geometry_columns TO PUBLIC;" # Enabling users to alter spatial tables.
sudo -u postgres psql   -d template_postgis1 -c "GRANT ALL ON spatial_ref_sys TO PUBLIC;"

然后需要使用创建的模板模板

创建数据库

sudo -u postgres createdb   database_name -T template_postgis1

Answer 3

对于任何人来说，如果你使用Postgis 2.0和PostgreSQL 9.1+，有一种更简单的方法：

#create your database if necessary and connect to it.
$ createdb  <db name>
$ psql <db name>

然后从psql shell运行：

CREATE EXTENSION postgis;
CREATE EXTENSION postgis_topology;
