BTW - If any windows users want to try the trunk version (PostGIS 2.0) -- we have experimental binaries (fairly recent as of last week)
Here http://www.postgis.org/download/windows/experimental.php Which includes lots more functions such as ST_MakeValid and ST_Split. As welll as Polyhedral Surface support and Raster support. The PostGIS Team is always very excited to squash bugs early. So please let us know if you find problems or have trouble using the binaries.
