Add a numeric column to your PostGIS table (in QGIS or any other client). 2. ""Open Table"" or ""Identify Features"" - see QGIS claims there are '0', instead of empty cells (NULL) in the column, although you did not enter them. Actually these zeros are not there. These *are* NULL cells. Only QGIS displays them bogus. This way you can't distinguish between cells really containing 0 and NULL. Moreover, you can't fill a NULL cell with a real 0 in QGIS - it will claim nothing changed in the table and won't let you save changes. r8213",bug,closed,critical: causes crash or data corruption,,Data Provider,Trunk,fixed,,,Yes,All,,0
