 I want to load a postgis view layer defined in a way that the OID
 represents the primary key of the view query result. No real primary key
 is defined in the source tables. When I query this view from psql it gives
 me the query result very fast. When I load this layer into QGIS it needs a
 very long time, more than 1 minute, to load this layer.
