     Type:  defect       |      Status:  new          
 Priority:  medium       |   Milestone:  PostGIS 2.1.5
Component:  postgis      |     Version:  2.1.x

 I have a simple table of points, which I want to view only those
 those points within a Polygon, and exclude those points outside of
 the polygon. The polygon is defined in a view that only contains
 the one polygon (actually VC17 - Surrey). If I issue in the WHERE
 clause the condition
 tetrad_records.the_geom && vc17.geom

 I get the expected result (i.e. only those points in the bounded box
 defined by the polygon. However, if the WHERE clause is (or any
 variant)
 ST_Within(tetrad_records.the_geom,vc17.geom)

 no records are returned. Ditto for ST_Contains and variants.
 Is this something I am doing wrong, or is it a bug.
 PostGis version 2.1.3 running under Windows 8.1 - 64 bit, and
 PostgreSQL 9.3.5
