PostGIS geometry editing

Goal: Implement ​PostGIS geometry editing functionality in GRASS GIS (wxGUI digitizer and v.edit module)

See also OGR Interface and wxGUI vector digitizer roadmap.

Tasks

• Attribute table (write) access for OGR-linked vectors (direct or linked by v.external)
• Improve OGR interface write access
• Implement PostGIS driver on the top of OGR driver to allow fully-featured editing (including topology)
• Add more...
