--------------------------------+---------------------------
Comment (by strk):
The bug seems to be fully inside ST_BuildArea, either it's a but there OR
the edges are not properly noded according to GEOS:
{{{
strk at strk=# select st_area(st_buildarea(st_collect(geom))) from
t6129_outer_ring_edges;
st_area
---------
(1 row)
strk at strk=# select st_area(st_buildarea(st_union(geom))) from
t6129_outer_ring_edges;
st_area
------------------------
0.00030558393262683487
(1 row)
}}}
The t6129_outer_ring_edges table is created by t6129_outer_ring_edges.sql
just attached
