Postgresql 17 Installation Error [2] on Windows 11

[sinanganiz]

I encountered an error while attempting to install PostgreSQL 17.0.1 on my Windows 11 machine. The error appears during the installation process, preventing successful completion.

Error Message: Problem running post-install step. Installation may not complete correctly The database cluster initialisation failed.

System Information:

Windows Version: 23H2
Build: 22631.4391

Executed the installation command in the terminal:
.\postgresql-17.0-1-windows-x64.exe --debugtrace debug.txt

Same problem here. I also couldn't find any service for Postgres running after the installation completed. I tried both Postgres 16 and 17 installation. I ran the installer "as admin". Running Windows 11.

Hi,
Please share the installation log from system location

[mortensimon]

install2-postgresql.log
I renamed the log file, otherwise untouched.

Thanks, I checked the log. The locale name has non-ASCII characters which are not supported by intidb. and hence the failure. We are looking into how to make installer list down the BCP 47 names. But there is no ETA atm

Is there something I can do on my side? Should I make a different locale when in the installation or do something with my Windows region/language?
