PostgreSQL version: 17.0
Operating system: Windows 10 & 11
Description:
With the latest Windows update, Microsoft has changed Turkish_Turkey.1254 to
Turkish_Türkiye.1254.
PostgreSQL installation gets an error during database and service creation,
and the database and Windows server are not created.
It seems to be related to the name changes in the locale.
