[GRASSLIST:3113] reclass vector in GRASS57

A newbie question for GRASS57:
I have a 500000-polygon vector map, each polygon having 8 attributes. I'm 
interested in attribute #3, for example: attribut #3 is an integer which can 
take value from 1 to 500.
I'd like to change the category of each polygon to the value of attribute #3, 
dissolving the boundaries at the same time (so that I would have 500 polygons 
at the end...)
What would be the command(s) to use to get what I want ?
Thanks a lot in advance
