Hello,

The filesystem is openzfs with native aes-256-gcm encryption:
https://openzfs.github.io/openzfs-docs/man/master/7/zfsprops.7.html#encryption

I've not tested if we get the same issue on another filesystem.

I don't face the issue on Ubuntu 20.04/openzfs 0.8/PostgreSQL 12, but I have fewer systems with this deployment.
On Ubuntu 22.04/openzfs 2.1.5/PostgreSQL 14, I face the issue from time to time, without knowing what triggers the error.

thanks for helping,

Nicolas.
