PostgreSQL version: 16.0
Operating system: Windows 11
Description:

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"

I wanted to completely uninstall and reinstall. However, I noticed that in
the language selection section during the installation, it said "Turkish,
Türkiye" instead of "Turkish, Turkey". I got the error: The installation
could not be completed, the cluster could not be created. When I wanted to
do manual initdb, I got the error "Turkish_Türkiye.1254" cannot be found.
After uninstalling the KB5031455 update, when I wanted to install it again
(This time language section is "Turkish, Turkey by the way), it was
successful. I think I encountered such a problem because the "Turkey"
expression on Windows changed to "Türkiye" with this update.
