Hi there,

My street table has road segment geometries from several jurisdictions.  The business rule requires me to build topology not for the entire table, but on a jurisdiction-by-jurisdiction basis.  I will need to re-generate the topology when geometry updates happen.

I can rebuild new topology, but that leaves old topology in the topo tables. So I want to remove the old topology before building new topology using topology.totopogeom for a jurisdiction. However, the constraints in and among the topology tables prevented me from the delete operation.

Since the topology is only managed by the postgis' topology engine, can I just remove some of the constraints?  This will not only allow deletion and but improve some operations as well?

Thanks!

Bo
