[postgis-users] Removing Interior Rings

I am attempting to simplify a series of polygons by buffering them and then
unioning the buffers together (sql below).
This works fine however, in some instances, there are interior rings (holes)
which I would like to remove.
I have tried Segmentize, but it failed to remove the interior rings.

Any suggestions would be appreciated.


create table orienteering_test with oids as
select geomunion(buffer(the_geom,0.0005)) as the_geom
from orienteering_all
where map_name = 'Tarrengower'
