#-- weight of edge in weight column.
#-- Essentially this returns the values (origid,destid pairs with optional weight) you put in, in this mode OQGRAPH looks very close to a real table. But it also does nothing special, it's just store/retrieve for those columns. The other columns will be returned as NULL.

#-- Find reachable vertices:
#-- SELECT * FROM foo WHERE latch = 1 AND origid = 1;
#-- Results:
#-- latch, origid, destid are same as input.

#-- Breadth-first search (latch=2, assumes that each vertex is weight 1)
#-- Find shortest path:
#-- SELECT * FROM foo WHERE latch = 2 AND origid = 1 AND destid = 6;
