QPSQL driver not loaded Qt

by

I came here googling because I had the same problem in Windows.

In my case to solve the issue I had to install PostgreSQL for Windows 32 bits since my Qt target was MinGW 32 bits.

Additionally, I had to add the PATH to the PostgreSQL bin and lib directories so Qt could find the right .dlls.

@SET PATH=C:\Program Files (x86)\PostgreSQL\9.6\bin\;C:\Program Files (x86)\PostgreSQL\9.6\lib\;%PATH%

The PATH can be set before launching Qt Creator or using the Qt Creator itself via the Build Environment in the Projects pane.
