I need to be able to change the setting to create default spatial columns from YES to NO in existing workbenches writing to PostGIS.
From this question (https://safe.secure.force.com/apex/AnswersQuestionDetail?id=906a0000000ciBiAAI) and Mark's answer:
Another setting that may help, when you add a new writer look at the properties dialog and there is a setting called "Create Generic Spatial Columns". As long as that is checked the table should be a generic one and not need a geometry type set.
I have been able to get my (new) workbenches to work the way I want them. However, I have a number of old workbenches with the option checked. When I connect my QGIS to PostGIS I see duplicate entries in the layer picker - one for the table with correct geometry and one for the table with unknown geometry. Can I retrospectively edit my workbench to change this setting?
Thanks
