<p class="MsoNormal"><span style="font-size:11pt;font-family:'Calibri Light',sans-serif">I am using the QGis python console for the use of exporting an active layer from postgist to a shape file
layer. <i> </i>I want to include the symbology as is possible through the GUI of QGis 2 (Dufour).<br>
I am using the <a href="http://www.qgis.org/api/classQgsVectorFileWriter.html#a289af78b5b609fbcb0572aaf505f2822" target="_blank">
<span style="color:windowtext;text-decoration:none">writeAsVectorFormat</span></a> method of the QgsVectorFileWriter class, but keep getting the message that there are “Too many arguments” as if the parameter doesn´t exist. That seems correct given the fact
that the mouse popup for the parameters doesn’t indicate a Symbology parameter. However in the official QGis API the parameter is mentioned:
<a href="http://www.qgis.org/api/classQgsVectorFileWriter.html#a1aac90d30d811d2888d1aab4098ad63c" target="_blank">
http://www.qgis.org/api/classQgsVectorFileWriter.html#a1aac90d30d811d2888d1aab4098ad63c</a>. The symbology parameter seems tob e added in the latest release (QGis 2)</span><u></u><u></u></p>
