Postgres - pg_catalog.pg_cast 업데이트시 권한이 거부되었습니다.

pg_catalog.pg_cast을 제한된 사용자 (Postgres 9.3)에서 업데이트하고 싶습니다.Postgres - pg_catalog.pg_cast 업데이트시 권한이 거부되었습니다.

update pg_cast set castcontext = 'i' where oid in (select c.oid from pg_cast c inner join pg_type src on src.oid = c.castsource inner join pg_type tgt on tgt.oid = c.casttarget where src.typname like 'int%' and tgt.typname like 'bool%');

오류와 함께 종료 :

그러나 내가 필요로하는 쿼리를 실행

ERROR: permission denied for relation pg_cast

그러나 권한이 올바르게 설정 될 것으로 보인다. 쿼리까지의 I는 DB 이후 단계 및 사용자 생성을 참조하십시오 : 나는 무엇을 더해야

psql -c "create database test1 WITH ENCODING 'UTF8' LC_COLLATE='en_GB.UTF8' LC_CTYPE='en_GB.UTF8' TEMPLATE=template0;" -U postgres 
psql -U postgres test1; 
test1=# CREATE USER test1 PASSWORD 'test1';

test1=# GRANT SELECT ON TABLE pg_catalog.pg_type TO test1; 
test1=# GRANT UPDATE ON TABLE pg_catalog.pg_cast TO test1;

sudo service postgresql-9.3 restart

의 test1 사용자와 쿼리 실행을 가능하게? 감사합니다. .
