postgresql – 在Amazon RDS上设置PostGis

create extension postgis;
create extension fuzzystrmatch;
create extension postgis_tiger_geocoder;
create extension postgis_topology;
alter schema tiger owner to rds_superuser;
alter schema topology owner to rds_superuser;

CREATE FUNCTION exec(text) returns text language plpgsql volatile AS $f$BEGIN EXECUTE $1; RETURN     $1; END; $f$;
SELECT exec('ALTER TABLE ' || quote_ident(s.nspname) || '.' || quote_ident(s.relname) || ' OWNER TO rds_superuser')
  FROM (
    SELECT nspname,relname
    FROM pg_class c JOIN pg_namespace n ON (c.relnamespace = n.oid) 
    WHERE nspname in ('tiger','topology') AND
    relkind IN ('r','S','v') ORDER BY relkind = 'S')
s;        

GRANT ALL PRIVILEGES ON DATABASE testgetwork TO luke;

然后我连接到数据库,并尝试加载我的新数据库的本地副本…

luke@l-xps:~$psql --host=myhost.dns.us-west-2.rds.amazonaws.com --port=5432 --username=luke --password --dbname=testgetwork < testgetwork.sql 
Password for user luke:

我的问题是,我该怎么办？所有的功能似乎被一个权限问题阻止,用户luke是rds_superuser组的一部分,任何有PostGis和RDS经验的人都知道如何纠正这个问题？
