#2610 closed defect (fixed)

ST_AddEdge* fails to use index on edge table on face split

Description

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)
