Existing PostGIS topology schema can be overwrite by --overwrite flag.
v.build.pg calls PostGIS functions:
v.out.ogr input=bridges output=PG:dbname=pgis_nc format=PostgreSQL
v.external input=PG:dbname=pgis_nc layer=bridges
v.info map=bridges ... |----------------------------------------------------------------------------| | Map format: PostGIS (PostgreSQL) | | DB table: public.bridges | | DB name: pgis_nc | | Geometry column: wkb_geometry | | Feature type: point | |----------------------------------------------------------------------------| ...
v.build.pg map=bridges ... Topology topo_bridges (6), SRID 900914, precision 1 10938 nodes, 0 edges, 0 faces, 10938 topogeoms in 1 layers Layer 1, type Puntal (1), 10938 topogeoms Deploy: public.bridges.topo ...
v.build.pg map=bridges
Creating new topology schema...
SELECT topology.createtopology('topo_bridges', \
find_srid('public', 'bridges', 'wkb_geometry'), 1)
Adding new topology column...
SELECT topology.AddTopoGeometryColumn('topo_bridges', \
'public', 'bridges', 'topo', 'point')
Building PostGIS topology...
UPDATE bridges SET topo = topology.toTopoGeom(wkb_geometry, \
'topo_bridges', 1, 1)
SELECT topology.TopologySummary('topo_bridges')
