Bug reference: 18648
Logged by: weijie JL
Email address: weijie1006jl@gmail.com
PostgreSQL version: 14.12
Operating system: RockyLinux 9
Description:

I used dnf to install PostgreSQL on a physical machine running Rocky Linux
9, and then performed a database restore using the pgBackRest tool. After
multiple experiments, I still found that there were index corruption issues
after the restore. Specifically, using amcheck to check the indexes resulted
in the following error: ERROR: XX002: item order invariant violated for
index "idx_template_xxxx_unique". However, this restore process does not
reproduce the issue on CentOS 7.9. The business impact of this index anomaly
is that when the query performs a full table scan, it can retrieve the
required data, but when using the index, the query results are empty.
