> * Install earthdistance operator from the contrib directory.
> * try this:
> cascade=> select null <@> '1,1'::point;

> ## The result I get:
> 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.

> before
> it's passed off a SQL statement like this.
