我喜欢这个，因为它可以一次性(在一个sql语句中)修改某个模式的表、视图、序列和函数所有者，而不需要创建函数，你可以直接在PgAdmin III和psql中使用它:

(在PostgreSql v9.2中测试)

DO $$DECLARE r record;
DECLARE
    v_schema varchar := 'public';
    v_new_owner varchar := '<NEW_OWNER>';
BEGIN
    FOR r IN 
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = v_schema
        union all
        select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = v_schema
        union all
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = v_schema
        union all
        select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = v_schema
    LOOP
        EXECUTE r.a;
    END LOOP;
END$$;

非常感谢。

更好的方法是:更改数据库和模式所有者。

DO $$DECLARE r record;
DECLARE
    v_schema varchar := 'public';
    v_new_owner varchar := 'admin_ctes';
BEGIN
    FOR r IN 
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = v_schema
        union all
        select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = v_schema
        union all
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = v_schema
        union all
        select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = v_schema
        union all
        select 'ALTER SCHEMA "' || v_schema || '" OWNER TO ' || v_new_owner 
        union all
        select 'ALTER DATABASE "' || current_database() || '" OWNER TO ' || v_new_owner 
    LOOP
        EXECUTE r.a;
    END LOOP;
END$$;

pg_dump as insert statements 
pg_dump -d -O database filename
-d ( data as inserts ) -O ( capital O is no owner )

然后使用以下命令将备份文件输送回PostgreSQL:

psql -d database -U username -h hostname < filename

由于没有包含所有者，因此创建的所有表、模式等都是在指定的登录用户下创建的。

我了解到这也是一个在PostgreSQL版本之间迁移的好方法。

很简单，试试看…

 select 'ALTER TABLE ' || table_name || ' OWNER TO myuser;' from information_schema.tables where table_schema = 'public';

Docker:修改所有表和序列的所有者

export user="your_new_owner"
export dbname="your_db_name"

cat <<EOF | docker run -i --rm --link postgres:postgres postgres sh -c "psql -h \$POSTGRES_PORT_5432_TCP_ADDR -p \$POSTGRES_PORT_5432_TCP_PORT -U postgres -d $dbname" | grep ALTER | docker run -i --rm --link postgres:postgres postgres sh -c "psql -h \$POSTGRES_PORT_5432_TCP_ADDR -p \$POSTGRES_PORT_5432_TCP_PORT -U postgres -d $dbname"
SELECT 'ALTER TABLE '||schemaname||'.'||tablename||' OWNER TO $user;' FROM pg_tables WHERE schemaname = 'public';
SELECT 'ALTER SEQUENCE '||relname||' OWNER TO $user;' FROM pg_class WHERE relkind = 'S';
EOF

根据elysch的回答，这里有一个针对多个模式的解决方案:

DO $$
DECLARE 
  r record;
  i int;
  v_schema text[] := '{public,schema1,schema2,schema3}';
  v_new_owner varchar := 'my_new_owner';
BEGIN
    FOR r IN 
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = ANY (v_schema)
        union all
        select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = ANY (v_schema)
        union all
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = ANY (v_schema)
        union all
        select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = ANY (v_schema)
        union all
        select 'ALTER DATABASE "' || current_database() || '" OWNER TO ' || v_new_owner 
    LOOP
        EXECUTE r.a;
    END LOOP;
    FOR i IN array_lower(v_schema,1) .. array_upper(v_schema,1)
    LOOP
        EXECUTE 'ALTER SCHEMA "' || v_schema[i] || '" OWNER TO ' || v_new_owner ;
    END LOOP;
END
$$;

在PostgreSQL中没有这样的命令。但是您可以使用我之前为GRANTs描述的方法来解决它。
