Hello, I've installed Debian 12 turnkey Linux with Postgresql 18.1 from the repository, but the PostgreSQL version is 15.1 and Debian 15.10. Is the image bad? Or what am I doing wrong? Thank you.
EDIT: I've upgraded to version 17.2 and its working..Its just for test purpuses.
Enter cat /etc/os-release to get the actual tunning Debian Version. The Version string is the Version string from the PostgreSQL package, it has nothing to do with the debian Version but is defined by the package maintainer before building the package and uploading it to debians Software repository.
I fail to see the ProxmoxVE specific question though
