 To reproduce, add any postgis layer, open layer properties, click on
 symbology, select "Unique Value" as the legend type.  The default
 classification field is the gid which isn't a reasonable choice.  I
 accidentally clicked the classify button without thinking on a very large
 postgis layer and it almost brought my machine down.
