     Type:  enhancement  |      Status:  new          
 Priority:  low          |   Milestone:  postgis 1.5.0
Component:  postgis      |     Version:  trunk

-------------------------+--------------------------------------------------
 The constructive function (union / difference) often create
 GeometryCollections, while people usually want a homogeneous result back
 (polygon, multilinestring, etc).  A helper function that takes in
 collection and outputs only the desired type would make it easier for
 people to do these operations entirely in the database.
