Description
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.

it's just starting with the first field. What would be the alternative?

Well, you could calculate the number of features that will be classified and warn that it will take a long time if there are more than x number of features. I'm not sure what the threshold would be, but it would stop the application (and maybe someone's computer) from freezing up.
