[postgis-users] Problem with Contains in Postgis 1.2.1

[Sean Ashton]

Hi All,
   I appear to have some problems when using Contains in Postgis 1.2.1, 
whereas the same
   query on Postgis 1.1.7 appears to work.

   I'm simply trying to work out if a point is within another region.
   My setup is as follows:
 	Setup 1. "POSTGIS="1.1.7" GEOS="2.2.3-CAPI-1.1.1" PROJ="Rel. 
4.4.9, 29 Oct 2004"
 	Setup 2. "POSTGIS="1.2.1" GEOS="2.2.3-CAPI-1.1.1" PROJ="Rel. 
4.4.9, 29 Oct 2004"

   When I run the following query
   select Contains(Buffer(GeomFromText('POINT(152.995672 
-27.483394)'),1),GeomFromText('POINT(152.995672 -27.483394)'))

   Setup 1 returns TRUE while Setup 2 returns FALSE.

   Is there a change in the way Contains works between 1.1.7 and 1.2.1?

   Could this be related to the
   	"Fix for bug in Within() caused by point-in-polygon performance 
shortcut." included in the 1.2.1 release?

   Any help would be appreciated.

   Sean
