[postgis-users] add a rank to population statistics- is this a case for a sequence?

[Robert Buckley]

Hi,

I have a table containing population statistics.

I would like to have an column which automatically updates the rank for each 
dataset. Would I somehow use a sequence to calculate this, or is there another 
way to do this?

thanks,

Rob
