geometry_dump — A composite type used to describe the parts of complex geometry.

`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 the`geom`

component. 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.
