[postgis-users] inside of a geometry

[Brent Pedersen]

hi, this may be a mapserver problem, but i'm trying to display the  
OUTLINE's of a polygon layer color coded according to an attributes.
the problem is that the adjacent polygons essentially share a border  
so only one of those polygon's border's is visible:
http://giifweb.cnr.berkeley.edu/fire/geoFRAP/060_247802000000.png    
(ignore the circle)

i tried using expand(the_geom, -0.1), but that doesn't work. is there  
a postgis to get the inner boundary of a polygon? (or a mapserver  
method to accomplish same?

thanks,
-brent
