I have uninstalled and reinstalled QGIS, deleted all qgis folders from the user/AppData folder, and still getting these errors any time I try to connect to my PostGIS server. I can connect to the server with browser and that works normally.

Python error : An error has occurred while executing Python code: See message log (Python Error) for more details.

Works fine here on a clean QGIS 3.4.2 installation on a clean Win10 (EN) installation.

#2 Updated by Christopher Hicks over 5 years ago

Turned out to be a server side issue. My HDD array failed and was causing inaccessibility for the PostgreSQL server.
