序列的 pg_dump 权限被拒绝

Question

我对倾销post-data部分有一个奇怪的问题。

转储命令是：

pg_dump -Fc --verbose --section=post-data --no-owner --no-acl -h localhost -p 9999 -U root db_name -W > constraints.dump

这是一条错误消息：

pg_dump: [archiver (db)] query failed: ERROR:  permission denied for relation verification_code_user_mapping_id_seq
pg_dump: [archiver (db)] query was: SELECT sequence_name, start_value, increment_by, CASE WHEN increment_by > 0 AND max_value = 9223372036854775807 THEN NULL      WHEN increment_by < 0 AND max_value = -1 THEN NULL      ELSE max_value END AS max_value, CASE WHEN increment_by > 0 AND min_value = 1 THEN NULL      WHEN increment_by < 0 AND min_value = -9223372036854775807 THEN NULL      ELSE min_value END AS min_value, cache_value, is_cycled FROM verification_code_user_mapping_id_seq

但是当我尝试在psql其中执行此查询时效果很好：

db_name=>  SELECT sequence_name, start_value, increment_by, CASE WHEN increment_by > 0 AND max_value = 9223372036854775807 THEN NULL      WHEN increment_by < 0 AND max_value = -1 THEN NULL      ELSE max_value END AS max_value, CASE WHEN increment_by > 0 AND min_value = 1 THEN NULL      WHEN increment_by < 0 AND min_value = -9223372036854775807 THEN NULL      ELSE min_value END AS min_value, cache_value, is_cycled FROM verification_code_user_mapping_id_seq;
             sequence_name             | start_value | increment_by | max_value | min_value | cache_value | is_cycled 
---------------------------------------+-------------+--------------+-----------+-----------+-------------+-----------
 verification_code_user_mapping_id_seq |           1 |            1 |           |           |           1 | f
(1 row)

以下是授予用户的权限root

db_name=> \dg root
                        List of roles
 Role name |          Attributes           |    Member of    
-----------+-------------------------------+-----------------
 root      | Create role, Create DB       +| {rds_superuser}
           | Password valid until infinity | 

我向公共模式中的所有表和序列授予了默认权限、select 和 all，但没有运气。

您能帮忙吗？提前致谢！

更新

db_name=> \dp verification_code_user_mapping_id_seq
                                              Access privileges
 Schema |                 Name                  |   Type   | Access privileges | Column privileges | Policies 
--------+---------------------------------------+----------+-------------------+-------------------+----------
 public | verification_code_user_mapping_id_seq | sequence | root=rwU/root     |                   | 
(1 row)

我正在使用 Amazon RDS。

可能是 AWS-RDS 特定的问题，但如果您明确指定要转储的架构，它就会起作用。

pg_dump -f lol.sql -Fc -v -n public -O -x --section=post-data -h 127.0.0.1 -p 9999 -U root db-name
