从备份恢复失败：创建 postgres 索引失败

[Dustin_Lang]

哇，如果升级过程能解决其中一些问题，那就太好了！

所以在安装了数据探索插件，并在 incoming_referers 索引中查看一番，并删除了此处查询列出的其他索引之后：

Corrupt indexes in PG12, how do I fix?

If a concurrent REINDEX fails because the table has invalid data, you need to: Fix the invalid data, like it was done here. List the invalid indexes using SELECT pg_class.relname FROM pg_class, pg_index WHERE pg_index.indisvalid = false AND pg_index.indexrelid = pg_class.oid; Drop each invalid index listed above using DROP INDEX <indexname>; Try the REINDEX again.

但我仍然遇到以下提示：

discourse=# REINDEX SCHEMA CONCURRENTLY public;
WARNING:  cannot reindex invalid index "pg_toast.pg_toast_19337_index_ccnew" concurrently, skipping
WARNING:  cannot reindex invalid index "pg_toast.pg_toast_19337_index_ccnew1" concurrently, skipping

而且这些索引也无法被删除！

# drop index pg_toast_19337_index_ccnew1;
ERROR:  index "pg_toast_19337_index_ccnew1" does not exist
