[postgis-users] Union of topologies

[Christopher Mutel]

Dear all-

Is there a way to create a new topology geometry as the union of two
existing topology geometries without casting to a normal geometry and
back? I have tried to write queries merging two TopoElementArrays, and
then use CreateTopoGeom, but so far without success.

Any help would be greatly appreciated.

Yours,
Chris
