Action: At first time when opening project on QGIS 3.4.5 and 3.6 versions needs credentials to connect to PostgreSQL DB.
Problem: But after that when connection is success with correct credentials the qgis repeatedly asks the same credentials again to connect to the same DB when the maps is zooming and moving and etc.
With QGIS 2.18, 3.4.0, 3.4.1 versions all works fine and don't asking repeatedly credentials after first correct time.
Maybe someone knows whats is wrong?
