[Qgis-user] Adding postgis views to qgis

[Piotr Kania]

Hi!

I just started to explore "postgis world" so sorry if my question is 
"silly".

In my postgis database I have multipolygon layer 'public.polygons' 
(gid,geom), I'd like to see vertices of those layer during editing, 
that's why I thought of postgis view. I create that in database:

CREATE VIEW points_of_polygons AS SELECT ST_DumpPoints(geom) AS geom 
FROM public.polygons;

But I can't add that view to Qgis, I found that info:

but I don't know how to use it, can anyone (step by step) explain how to 
do that? Thanks
