toTopoGeom: ERROR: duplicate key value violates unique constraint "relation_layer_id_key"

Reported by: strk Owned by: strk
Priority: critical Milestone: PostGIS 2.0.1
Component: topology Version: 2.0.x
Keywords: Cc:


I don't know what's going on but a single call to toTopoGeom is triggering a "relation_layer_id_key" violation. The starting "relation" table is _empty_

select totopogeom('0105000000020000000102000000030000000000000000E065C002000000008056C001000000004065C0041AD965BE5554C002000000000064C0011AD965BE5554C001020000000200000000000000004065C0031AD965BE5554C00000000000E065C000000000008056C0', 'hextopo', 1);

Ah, ok, clear… TopoGeo_addLinestring returns a SET of primitive identifiers, and it's returning the same identifier more than once …

Not sure if we should omit the duplicates from the TopoGeo_addlinestring itself or from the caller…

Oh, it's not even that, but toTopoGeom calling TopoGeo_addLinestring two times, and the second time it gets the same result as the first time. At least we restrict the focus on toTopoGeom
