> implementation of some functions for converting from GeoHash 
> strings to box2ds and geometries and such. I've attached a 
> patch that adds a few functions for GeoHash input along with 
> some regression tests. I haven't written up any documentation 
> yet as this is really kind of a first-pass and my first 
> attempt at a PostGIS patch, so have at it and see if it's 
> relatively sane and I'll get to the documentation next.
> I've made the patch against the current svn head at r9732 via 
> strk's github repository.

> The patch itself contains the following functions:
> 
> ST_Box2dFromGeoHash(geohash text [, precision int4 default 
> null]) ST_GeomFromGeoHash(geohash text [, precision int4 
> default null]) ST_PointFromGeoHash(geohash text [, precision 
> int4 default null])
> 
> Where the default precision is the full precision of the GeoHash.
