修复损坏的数据库PostgreSQL

问题描述

我的postgresql数据库出现多个错误，这是在电涌后导致的：

I have multiple errors with my postgresql db, which resulted after a power surge:

我无法从数据库访问大多数表。例如，当我尝试从ac_cash_collection中选择 select * 时，我得到了愚蠢的错误：

I cannot access most tables from my database. When I try for example select * from ac_cash_collection, I get the foolowing error:

ERROR: missing chunk number 0 for toast value 118486855 in pg_toast_2619

我遇到以下错误：

Error message from server: ERROR:  relation "public.st_stock_item_newlist" does not exist
pg_dump: The command was: LOCK TABLE public.st_stock_item_newlist IN ACCESS SHARE MODE

我继续尝试对整个数据库进行重新索引，实际上我离开了它，进入睡眠状态，发现它在数据库中没有做任何事情。早上，所以我不得不取消它。

I went ahead and tried to run reindex of the whole database, I actually I left it runnng, went to sleep, and I found it had not done anything in the morning, so I had to cancel it.

我需要一些帮助来尽快解决此问题，请帮助。

I need some help to fix this as soon as possible, Please help.

我不知道它们是否对烤面包机有所帮助。无论如何，如果设置它们会导致您的数据库再次可用，我将{backup + drop + restore}使所有表和目录再次恢复为新生状态。成功！

I don't know if they help against toast-tables. In any case, if setting them causes your database(s) to become usable again, I would {backup + drop + restore} to get all tables and catalogs into newborn shape again. Success!
