PG_FUNCTION_INFO_V1 ( pgis_union_geometry_array  )

This is the final function for GeomUnion aggregate.

Will have as input an array of Geometries. Will iteratively call GEOSUnion on the GEOS-converted versions of them and return PGIS-converted version back. Changing combination order might speed up performance.
