Also (and this relates to a previous question of mine) if I have imported a postGIS vector layer via v.in.ogr, does that create a permanent link so that edits via v.digit are then written back to the SQL database? Or do I need to somehow tell it to update?
v.in.ogr imports the layer into GRASS as GRASS format, so there is no more link to the geometry elements contained in your postgis table.
You can just link a postgis layer into v.external, but then it is "read-only".
If you want to work directly on the geometry in a PostGIS layer, you will have to use QGIS, uDig or gvSIG.
