Cort et. al,

Thanks for pointing that out. We'll be releasing a new update of wktraster binaries probably late this week or early this weekend.

FYI - a number of improvements have been made since that last binary release. For one, there is now an ST_Intersects and ST_Intersection functions.

Some memory leaks have also been addressed that made ST_DumpAsPolygons slower than it should be.

Also check out Pierre's tutorial

If you happen to be at FOSS4G this year, both Pierre Racine and Jorge Arevalo will be giving talks on PostGIS WKT Raster
