[Qgis-user] problems running processing.runalg('qgis:voronoipolygons', <postgis-layer>), processing.runalg('qgis:importintopostgis', ...)

[Marco Lechner - FOSSGIS e.V.]

Hi,

1. i try to run qgis' voronoipolygons algorithm from processing toolbox 
in a python script (processing-script or standalone)

For testing I loaded a shape and a postgis layer to a 
QgsMapLayerRegistry. I can sucessfully run 
processing.runalg('qgis:voronoipolygons', <shape-layer>, 0, outShpVec) 
but processing.runalg('qgis:voronoipolygons', <postgis-layer>, 0, 
outShpVec) fails (with exit code 137 :-( ). No message in debugging 
console in my IDE (PyCharm).

Any idea or example why this does not work or how I can do further 
investigation?

2. I'm in trouble using the qgis:importintopostgis via script as well. 
It expects an Index of a registered postgis connection. How can I use 
this alg by passing the connection params directly or do I have to 
create an entry in QSettings() for that and how can I get the latest 
registered connection than?

Thank you

Marco
