恢复PostgreSQL数据库时创建SEQUENCE时出错

Question

UserX有以下授权:

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

关于我做错什么的任何建议？

Answer 1

您正在尝试将转储从v10数据库恢复到较旧版本的PostgreSQL(CREATE SEQUENCE ... AS在v10中是新的).

这是不受支持的,也不会起作用.您可以使用pg_restore手动创建SQL脚本并对其进行编辑.或者升级目标数据库.

我记下了这些笔记：

支持所有压缩数据库

pg_dump -U {usuario} -h {host} -W {database} | gzip -c > 存档.gz

从后面的 GZIP 恢复

gunzip -c {archivo.gz} | psql -h {host} -U postgres {database}

从 GZIP 备份从 v10 恢复到 v9.x

gunzip -c {archivo.gz} | sed -e '/AS 整数/d' | psql -U postgres -h {host} -W {database}
