[postgis-users] Points to Raster

Dear List,

I have a simple point geometry table in PostGIS that holds a value in its
VALUE column. I was wanting to convert this x,y point table into a raster
table or a raster file (png)and use this VALUE Column to assign the value to
the pixel. I was trying to use the ST_AsRaster command but I could not get
it to work. Can someone please give me an example on how to convert an
existing table of xy points in PostGIS called MY_POINTS into a raster table
called MY_RASTER or a png file?
