Hello, with the Windows KB5031455 update, the name of the character set from Turkish_Turkey.1254 was changed to "Turkish_Türkiye.1254" and PostgreSQL Servers are not working. Even clean installations of the Latest Version give errors.
I don't know much about your Github build, so I wanted to give information here.
Error running C:\Windows\System32\cscript //NoLogo "C:\Program Files\PostgreSQL\16/installer/server/initcluster.vbs" "NT AUTHORITY\NetworkService" "postgres" "****" "C:\Users\*************\AppData\Local\Temp/postgresql_installer_416b328eab" "C:\Program Files\PostgreSQL\16" "C:\Program Files\PostgreSQL\16\data" 5432 "Turkish,Türkiye" 0: Program ended with an error exit code
Problem running post-install step. Installation may not complete correctly
The database cluster initialisation failed.
