Reported by: strk Owned by: strk
Priority: medium Milestone: PostGIS 2.4.10
Component: topology Version: 2.4.x

Description

The following snippet results in an exception: 

select createtopology ('tt', 0);
select topogeo_addpoint('tt', 'POINT(0 0)');
select topogeo_addlinestring('tt', 'LINESTRING(0 -0.1,1 0,1 1,0 1,0 -0.1)'::geometry, 1);

Exception is: ERROR: Invalid edge (no two distinct vertices exist)

This probably happens also in PostGIS-2.4
