PostGIS function for a random point inside a polygon -- page on PostGIS wiki

I have created a page on PostGIS wiki with the description of the random point functions: http://trac.osgeo.org/postgis/wiki/UserWikiRandomPoint

PostGIS function for a random point inside a polygon -- REVISED

This is a revised random-point-in-polygon function first discussed in my earlier post. It turns out that in some weird cases (multipolygons consisting of a number of small and disperse polygons) the function takes too many iterations to complete. Below is a code for another function called RandomPointMulti that addresses this problem. RandomPointMulti breaks a multipolygon into polygons, randomly chooses a polygon with the probability proportional to the area of the polygon, and then calls original RandomPoint on that polygons. RandomPoint was also modified: some typos have been fixed, exception is thrown if the max number of iterations has been exceeded, and and max number of iterations can be specified as an argument.
