#2610: ST_AddEdge* fails to use index on edge table on face split
----------------------+-----------------------------------------------------
Reporter: strk | Owner: strk
Type: defect | Status: new
Priority: medium | Milestone: PostGIS 2.1.2
Component: topology | Version: 2.1.x
Keywords: |
----------------------+-----------------------------------------------------
The edge table update on face split fails to make use of the edge table
index by passing the return of ST_LineInterpolatePoint(geom) and a literal
to ST_Contains.
As a result, topology population has poor scaling performance.
See http://lists.osgeo.org/pipermail/postgis-
devel/2014-January/024076.html
... I wonder how could such a defect be put under regression testing ...
(or we'll need a performance testsuite)
