由于权限，无法使用pg_dump转储Django数据库

Question

我想将PostgreSQL数据库转储到SQL文件中。这是pg_dump DB_NAME > dump.sql命令结果：

pg_dump: [archiver (db)] query failed: ERROR:  permission denied for relation django_migrations
pg_dump: [archiver (db)] query was: LOCK TABLE public.django_migrations IN ACCESS SHARE MODE

当我想列出关系时：

postgres=# \d
No relations found.

架构列表：

                          List of schemas
  Name  |  Owner   |  Access privileges   |      Description       
--------+----------+----------------------+------------------------
 public | postgres | postgres=UC/postgres+| standard public schema
        |          | =UC/postgres        +| 
        |          | root=U/postgres     +| 
        |          | secretusr=U/postgres | 
(1 row)

数据库列表：

                                  List of databases

           |          |          |             |             | postgres=CTc/postgres +
           |          |          |             |             | secretusr=CTc/postgres+
