pg_dump备份失败，错误信息提示pg_dump: [archiver (db)] query failed: ERROR: schema "pgs_distribution_metadata" does not exist
用pg_dump备份失败，错误信息提示pg_dump: [archiver (db)] query failed: ERROR: schema "pgs_distribution_metadata" does not exist
[postgres@node1 backup]$ pg_dump -Fc shop > shop.dump
pg_dump: [archiver (db)] query failed: ERROR: schema "pgs_distribution_metadata" does not exist
pg_dump: [archiver (db)] query was: COPY public.chars (chr) TO stdout;
postgres=# dn
List of schemas
Name | Owner| pgs_distribution_metadata | postgres |
| public | postgres |
(2 rows)
尝试删除 pgs_distribution_metadata，后再试
postgres=# drop schema pgs_distribution_metadata cascade;
ERROR: cannot drop schema pgs_distribution_metadata because extension pg_shard requires it
HINT: You can drop extension pg_shard instead.
postgres=# drop extension pg_shard cascade;
DROP EXTENSION
postgres=# dn
List of schemas
| Name | Owner |
|---|---|
| public | postgres |
(1 row)
同事注释掉postgresql.con里关于pg_shard的相关设定，
shared_preload_libraries = 'pg_shard' # (change requires restart)
restart后再试，用pg_dump备份依然失败
[postgres@node1 backup]$ pg_dump -Fc shop > shop.dump
pg_dump: [archiver (db)] query failed: ERROR: schema "pgs_distribution_metadata" does not exist
pg_dump: [archiver (db)] query was: COPY public.chars (chr) TO stdout;
寻求解决办法，谢谢！

德哥，谢谢你的回复。
我shop库的owner也是postgres。[postgres@node1 backup]$ psql
psql (9.4.1)
Type "help" for help.postgres=# set
AUTOCOMMIT = 'on'
PROMPT1 = '%/%R%# '
PROMPT2 = '%/%R%# '
PROMPT3 = '>> '
VERBOSITY = 'default'
VERSION = 'PostgreSQL 9.4.1 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4), 64-bit'
DBNAME = 'postgres'
USER = 'postgres'
PORT = '5432'
ENCODING = 'LATIN1'

pg_dump: [archiver (db)] query was: COPY public.customer_reviews (customer_id, review_date, review_rating, review_votes, review_helpful_votes, product_id, product_title, product_sales_rank, product_group, product_category, product_subcategory, similar_product_ids) TO stdout;麻烦你帮助详细解释一下该问题的发生原因及解决方案，谢谢！

公益是一辈子的事, I am digoal, just do it. 阿里云数据库团队, 擅长PolarDB, PostgreSQL, DuckDB, ADB等, 长期致力于推动开源数据库技术、生态在中国的发展与开源产业人才培养. 曾荣获阿里巴巴麒麟布道师称号、2018届OSCAR开源尖峰人物.你备份的是shop库，所以在postgres库操作是没用的。
