Correct it will dissolve overlapping regions, though you still may end up
with multipolygons if you have islands of polygons.

Sorry, the LIMIT was for testing purposes (since there might be a few
hundred to thousand) polygons in the return set. 

What I am hoping is that the UNION will simplify the resulting polygon as
much as possible (just the ourside boundary). 

Is that correct? (given that there are no holes).
