[Qgis-user] QGIS project templates and PostGIS connections

[Bo Victor Thomsen]

This answer is somewhat old; there might be a better solution:

https://gis.stackexchange.com/questions/247454/simplify-postgis-authentication-process-from-qgis

and directory .qgis2 is replaced by a profile directory:  Menu item 
"Settings"->"Open Active Profile Folder"

Med venlig hilsen / Kind regards
