[postgis-devel] a slight error in postgis TopologySummary

[Rémi Cura]

Hello,
I noticed a slight error in the TopologySummary function :
The layer count is wrong : it appears that if a layer is empty it is not
counted.

Cheers,
Rémi-C

Here is what I get :

SELECT TopologySummary('demo_zone_test')
Topology demo_zone_test (11), SRID 931008, precision 0.1, has Z
88 nodes, 105 edges, 49 faces, 76 topogeoms in 2 layers
Layer 1, type Lineal (2), 48 topogeoms
 Deploy: demo_zone_test.route_demo.tg
Layer 4, type Polygonal (3), 28 topogeoms
 Deploy: demo_zone_test.bati_demo.tg
Layer 5, type Polygonal (3), 0 topogeoms
 Deploy: demo_zone_test.chaussee.tg
