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 references to a component geometry - 
     
path[]- a 1-dimensional integer array that defines the navigation path within the dumped geometry to thegeomcomponent. The path array starts at 1 (e.g.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.
