User Error: Missing enviroment path to LIBPQ.DLL

Hello,
It seems that the default Qt installation on Windows cannot load some of the core plugins.
Here is an output from having enabled QT_DEBUG_PLUGINS env var.

- Windows is entirely up to date.
- Debugging tools for Windows is installed and working correctly.
- MS Visual Studio 2015 is installed and up to date.
- No other weirdness.
I've reported this as a bug assuming assume that a fresh install should not have issues loading plugins. If this is incorrect or I've made an error please let me know.
Thank you for this wonderful platform and the amazing work that goes into it.
