Description

following this : http://oslandia.com/en/2017/10/07/refresh-your-maps-from-postgresql/.
I checked the two boxes in the rendering tab, and used 'refresh qgis' message.
Then in a psql shell, I write listen qgis,
I import a shp in my database,
I write Notify qgis, 'refresh qgis' ;
All that I get in return is : Asynchronous notification "qgis" with payload "refresh qgis" received from server process with PID 1848
And the canevas is unchanged.
Did I miss something ?

Postgres 9.3 ; qgis 2.99 ; windows 7

Qgis 3.4.2, postgres 9.6, postgis 2.3, windows 7

I followed the same method to get the map refreshed automatically but unsuccessfully.
I tried with an import and an update on a feature this time,
each time I wrote NOTIFY QGIS, 'refresh qgis' in psql,
no change in the map.
