[postgis-devel] Minor fix in distance_sphere

[Charlie Savage]

Try this:

select distance_sphere('SRID=4326;POINT(-104.9664 39.7055)'::geometry,
  	               'SRID=4326;GEOMETRYCOLLECTION(EMPTY)'::geometry)


And the result is this:

ERROR:  lwpoint_deserialize: attempt to deserialize a point which is 
really a Invalid type


The error message is incorrect, besides being a bit worrisome.  The 
correct error message should be:

ERROR: lwpoint_deserialize: attempt to deserialize a point which is 
really a GeometryCollection


Patch attached,

Charlie
