I saw this post:Routing issues with pgrouting, and try the ability of reverse_cost.

As the result of this post, if there is only one way to go from one node to another, even though the reverse_cost is very huge, pgRouting can still give the result the same as the one that I do not use reverse_cost(but this time the cost is drastically huge), but apparently it's unreasonable.

Then I try to set the reverse_cost to negative value, unfortunately under Win7 the error occurs:

Can someway I can do to solve this problem?

Or under this condition can pgRouting return one acceptable and operable result like "route not found" or "route not connected"?

Forget about pgRouting. There are lots of other things you should check.

  • Check if your LAN cable is plugged or WiFi is connected.
  • Check if your PostgreSQL server is working properly.
  • Check if your connection host/port to PostgreSQL is set correctly.
  • Check if your machine or PostgreSQL server is ignoring port 5432.
