恢复PostgreSQL数据库时创建SEQUENCE时出错

Babak 发表于 Dev

半

UserX具有以下授予：

CREATE ROLE "UserX" LOGIN PASSWORD 'pass';
CREATE DATABASE "DBX" WITH OWNER="UserX" ENCODING='UTF8' TABLESPACE=pg_default CONNECTION LIMIT=-1;
GRANT CONNECT ON DATABASE "DBX" TO "UserX";
GRANT USAGE ON SCHEMA public TO "UserX";
GRANT SELECT,INSERT,UPDATE,DELETE ON ALL TABLES IN SCHEMA public TO "UserX";
ALTER DEFAULT PRIVILEGES GRANT ALL ON TABLES TO "UserX";
ALTER DEFAULT PRIVILEGES GRANT ALL ON SEQUENCES TO "UserX";

尝试将其转储还原到其他数据库时出现以下错误：

pg_restore: creating SEQUENCE "public.tblX_Id_seq"
pg_restore: [archiver (db)] Error from TOC entry 218; 1259 438745 SEQUENCE tblX_Id_seq UserX

关于我做错了什么建议吗？

您正在尝试将转储从v10数据库还原到旧版本的PostgreSQL（CREATE SEQUENCE ... ASv10中的新增功能）。

那不被支持，将不起作用。您可以使用创建SQL脚本pg_restore并进行手动编辑。或升级目标数据库。
