Question

我正在测试我的备份/恢复过程，当我恢复数据库时，所有表都是正确的以及数据和表所有权。但是我担心会有一些警告/错误。

我的备份使用postgres crontab在cronjob中运行。然而，postgres cronjob中的pg_dump命令是使用＆＃39; myuser＆＃39;用户：

00 01 * * * pg_dump -U myuser -Fc --exclude-table-data=example_table example_db > ~/backups/example_db_backup.gz

如您所见，我在备份期间从其中一个表中排除数据。所有其他表等都会正常备份。

然后我使用postgres用户创建一个新的测试数据库，因为我不想将其恢复到实时数据库。我授予＆＃39; myuser＆＃39;的新数据库完全访问权限。用户然后恢复db：

su postgres
psql -U postgres
create database test;
GRANT ALL PRIVILEGES ON DATABASE test TO myuser;
\q

然后我按如下方式恢复数据库：

pg_restore -d test -U myuser ~/backups/example_db_backup.gz

如上所述，恢复正常，数据库中的所有内容都显示正确，但在恢复期间，我收到以下消息：

pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 2655; 0 0 COMMENT EXTENSION plpgsql 
pg_restore: [archiver (db)] could not execute query: ERROR:  must be owner of extension plpgsql
Command was: COMMENT ON EXTENSION plpgsql IS 'PL/pgSQL procedural language';

pg_restore: WARNING:  no privileges could be revoked for "public"
pg_restore: WARNING:  no privileges could be revoked for "public"
pg_restore: WARNING:  no privileges were granted for "public"
pg_restore: WARNING:  no privileges were granted for "public"
WARNING: errors ignored on restore: 1

这些错误是否值得关注？即使恢复似乎工作正常，我也不喜欢忽略我不理解的潜在问题。

加载sql dump文件时出现相同的错误，

 int val;
 int val2;
 Int32.TryParse(category.SelectedValue.ToString(), out val);
 Int32.TryParse(type.SelectedValue.ToString(), out val2);

 SqlConnection conn = new SqlConnection();

为您的postgres=# alter role <user-name> superuser;用户提供superuser角色，

pg_restore工作正常，但有一些错误
