#673 closed enhancement (fixed)

Add support for typed empty geometries

Reported by: strk Owned by: strk
Priority: low Milestone: PostGIS 2.0.0

Description

GEOS supports typed empty geometries. Postgis doesn't. For ST_SharedPaths it might be nice to have it, as GEOS would return a COLLECTION with 2 MULTILINESTRING elements, both possibly empty. So this would be a valid, and defined result: 

 COLLECTION(MULTILINESTRING EMPTY, MULTILINESTRING EMPTY)

r6235 allows typed empty collection coming from geos to be retained in postgis. regression testsuite survives that.
