如何从远程服务器pg_dumpall到本地计算机和本地计算机到远程服务器

Question

我需要进行新安装，我需要从当前安装复制数据库。我需要pg_dumpall命令将远程服务器连接到本地计算机。

我已经尝试过了，但是它仅适用于转储，不适用于dumpall

pg_dump -h hostname -Fc -o -U username database > databaseall.sql

和

pg_dumpall -h hostname -p 5432 -U username > databaseall.sql

给出错误

pg_dumpall: query failed: ERROR:  permission denied for relation pg_authid
pg_dumpall: query was: SELECT oid, rolname, rolsuper, rolinherit, rolcreaterole, rolcreatedb, rolcanlogin, rolconnlimit, rolpassword, rolvaliduntil, rolreplication, rolbypassrls, pg_catalog.shobj_description(oid, 'pg_authid') as rolcomment, rolname = current_user AS is_current_user FROM pg_authid ORDER BY 2

和

pg_dumpall -h hostname -p 5432 -U username -c -o -f "databaseall.sql"

给出错误

pg_dumpall: query failed: ERROR:  permission denied for relation pg_authid
pg_dumpall: query was: SELECT rolname FROM pg_authid ORDER BY 1

Answer 1

使用pg_dumpall / psql命令转储和还原

pg_dumpall > alldb.sql

载入另一个实例

psql -f alldb.sql postgres
