After i  type in command prompt next command

но её версия отличается от версии initdb.

Hi, 

The error shared by you, states that the installation completed, however, the DB cluster initialization failed.

Could you please check the below things :

- The permissions are set correctly on the data directory.
- No antivirus is running on the server as it might cause the issue.
- Create the DB cluster manually using the initdb utility.

Also, could you please share the installation logs with us for the analysis.
