[postgis-users] Saving a split polygon

[Peter Brown]

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).
There are workarounds for this (e.g. convert to 'Shape' files) but they
seem incredibly clumsy. Does anyone have a more direct solution?
Thanks
Peter Brown
