[postgis-devel] Topology allow more than one layer with same topocolumn-name

[aperi2007]

In the topology,
actually is possible to do this:

SELECT topology.CreateTopology('ma_topo',4326, 0.00005);
SELECT topology.AddTopoGeometryColumn('schema-of-topology', 
'schema-of-layer', 'linear_layer1', 'topo_name_column', 'LINE');
SELECT topology.AddTopoGeometryColumn('schema-of-topology', 
'schema-of-layer', 'linear_layer2', 'topo_name_column', 'LINE');
SELECT topology.AddTopoGeometryColumn('schema-of-topology', 
'schema-of-layer', 'poligonal_layer3', 'topo_name_column', 'POLYGON');

So I add three layer every one having the same topo-column name.
I don't understand if this is a correct situation or not.

I believe three layers must have three distinct topocolumn names if use 
the same topology

don't ?

Thx,

Andrea.
