Обсуждение: [7.0.2] should this work? geo_distance() ...

SELECT geo_distance(location::point,'(-79.412636,43.720768)'::point) FROM location_table;

where location is defined as point already?

I'm getting:

pqReadData() -- backend closed the channel unexpectedly.       This probably means the backend terminated abnormally
  before or while processing the request.
 
The connection to the server was lost. Attempting reset: Failed.

each time ... its producing a core that I've yet to analyze,as I have to
compile a new debugging server to do so.  figured I'd check first that
what I'm trying to do is possible, before I try and 'bark up the wrong
tree' ...

thanks ...

appendum:

If I add a WHERE to it, it works fine ... its only when I try to do
*everyone* that it screws up:

SELECT geo_distance(location::point,'(-79.412636,43.720768)'::point)  FROM personal_data WHERE gid = 14215;
  geo_distance
