PostgreSQL version: 10.5
Operating system:   Windows
Description:

The EDB Windows installer says it installs version 10.5, but once installed
the list of installed packages (Control Panel\All Control Panel
Items\Programs and Features) only shows a version of 10. This makes it quite
hard for configuration management systems like Salt or Puppet to decide
whether a minor version update needs to be executed or not. Because of this,
Windows installers should always register the exact version number for the
package.
