I just got a new computer, installed clean Windows 11 and all updates.
Before installing the KB5031455 update, I installed PostgreSQL v16. During
the installation, I selected "Turkish, Turkey" as the language and it was
successful, the service started working. However, after installing the
KB5031455 Update, I could not start the PostgreSQL server service. There was
the following error in Event Viewer:

"FATAL: configuration file "C:/Program
Files/PostgreSQL/16/data/postgresql.conf" contains errors"

This is not a bug.  You added something illegal to "postgresql.conf",
and the server refuses to start without a valid configuration.
Edit the file and fix the problem.
The error message should give you details about what was wrong.

No, i did not add anything to postgresql.conf file. Like i said before,
there is a problem with that Windows update.

Hm.  The Windows installer is not maintained by PostgreSQL, but by
EnterpriseDB.  Perhaps one of them is on the list and can comment, but
it is not a PostgreSQL bug that the project can fix.

I installed the update again to double check. When the update is installed,
PostgreSQL stops and cannot be started. I saw another error message on the
event viewer that Turkish_Türkiye.1254 (it should be Turkish_Turkey.1254)
could not be found. As soon as I uninstall the update, the server becomes
running again.

Well, perhaps the installer added something problematic to "postgresql.conf"?
You didn't quote the literal error message, but I'd search for "Türkiye".
Perhaps the "ü" was in a wrong encoding.
