[postgis-users] Need help on query to return boundary of polygon

I would like to return the boundary of a selected polygon, and I can't seem to get my syntax correct.  What I want to do is to select the boundary from a polygon table of towns, where the town name equals a selected town.  Something like this:
Select ST_Boundary(geom) from (select * from towns where towns.townname='Mytown')
-obviously this is not correct, but hopefully gives an idea of what I want.

Any suggestions?
