[postgis-users] server termentaes abnormaly dijkstra

[Jason R. Moore]

I had the shortest path functionality working form pgdijkstra.  I tried 
making a php front end for it, (gave up because php would not connect 
using the same connection string as mpserver uses) then tried a pearl 
front end  and  now when I try and run it manually from psql I get the 
flowing:

 SELECT shortest_path('SELECT source, id, target, cost FROM 
tiger_39_edges', 82730 , 82880 , false, false);
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.

I have tried the smaller data set/demo that comes with pgdijkstra and it 
still crashes.  Also I tried reinstalling the pgdijkstra library and 
scrips and it still crashes.

Is their an easy fix? if not what is the best way of backing up only the 
data and purging pgsql?
