geometry_dump
Name
geometry_dump — A composite type used to describe the parts of complex geometry.
Description
   
    geometry_dump
   
   is a
   
    composite data type
   
   containing the fields:
  
- 
     
geom- a geometry representing a component of the dumped geometry. The geometry type depends on the originating function. - 
     
path[]- an integer array that defines the navigation path within the dumped geometry to thegeomcomponent. The path array is 1-based (i.e.path[1]is the first element.) 
   It is used by the
   
    ST_Dump*
   
   family of functions as an output type to explode a complex geometry into its
		constituent parts.
