<div dir="ltr">In Quantum GIS (QGIS) there is a very useful facility for taking a polygon in a PostGIS database linked to QGIS and splitting it. HOWEVER, when one then tries to save the two portions, PostGIS puts up an error message that it cannot save the new portion because it does not have a new ID (it can save the existing portion, because this is only an edit of an existing ID). <div>
There are workarounds for this (e.g. convert to 'Shape' files) but they seem incredibly clumsy. Does anyone have a more direct solution?</div><div>Thanks</div><div>Peter Brown<br><div> </div></div></div>
