没办法使用其他用户名从pg_dump恢复photoshopql数据库
问题说明
我需要从computer1中以postgres用户名1转储一个postgres数据库，然后在具有postgres用户名2的computer2上恢复它.我一直遇到似乎备份文件要使用username1的错误:
I need to dump a postgres database from computer1 with postgres username1 and then restore it on computer2 with postgres username2. I keep running into the error that looks like the backup file wants to use username1:
当我在computer2上运行它时:
When I run this on computer2:
psql dbname < backupname.pgsql
我收到此错误:
ERROR: role "username1" does not exist
我尝试过:
// Dumping from computer1:
pg_dump dbname > backupname.sql
pg_dump dbname > backupname.pgsql
pg_dump -U username1 dbname -N topology -T spacial_ref_sys > backupname.pgsql
// Restoring on computer2:
psql dbname < backupname.pgsql
是否需要对转储或还原进行修改以克服此问题?
Is it the dumping or the restoring that needs to be modified to get past this?
正确答案
问题出在转储上.通过此帖子的见识，我能够解决此问题使用:
The problem is with the dumping. With insight from this post I was able to resolve this using:
// On Computer1
pg_dump dbname -O -x > backupname.sql
// On Computer2
psql dbname < backupname.sql
与pg_dump一起使用的选项标志是:
The option flags used with pg_dump are:
-O <-- No owner
Do not output commands to set ownership of objects to match the original database
-x <-- No privileges
Prevent dumping of access privileges (grant/revoke commands)
有关更多信息，请参见 PostgreSQL文档pg_dump 选项标志.
See the PostgreSQL docs for pg_dump for more info on the option flags.
