I wish to edit and remove qgsfeatures in qgsvectorlayer. Vectorlayer contains postgis table.
QgsVectorDataProvider::capabilitiesString() returns the folowing string:Add Features, Add Attributes, Delete Attributes, Fast Access to Features at ID, Simplify Geometries, Simplify Geometries with topological validation
So it looks like I can only add new features, not edit/delete already created.Why?
