DB corruption upon restart

[Resousse]

Description

Inside a percona pg-db pod, the database container restarted properly, and after the restart, database was corrupted. All my tables are encrypted using pg_tde.

Expected Results

A reindex can solve the issue, but I have the feeling (as it occurred 3-5 times the past week), that it occurs at any restart of the DB

Actual Results

Leading to the following error after the restart

tenants=# select * from sessions;
ERROR:  invalid page in block 0 of relation "base/16593/17596"

Version

Percona PG 18 installed via helm charts (both pg-db and pg-operator in 2.8.2). I don't know what is the version of pg_tde.

Steps to reproduce

Not always replicable, but one restart of the DB some writes in it
