postgis - How to display vertex markers in QGIS for non-editable layers?

I've a PostGIS layer with read-only privileges. Is there any way to display the vertex markers of the layer?

Answer

No need to create a new layer. You can show your layer's vertices using the Outline: Marker line Symbol layer type.

Just add a new symbol layer

• Add a new symbol layer;


• Choose Outline Marker line (top right corner);


• In the Marker placement, Choose "On every vertex"

You can even style the marker to look like the red cross symbol used on layers in edit mode.
