The following bug has been logged online: Bug reference: 3720 Logged by: M. Palm Email address: m.palm@geoinsoft.de PostgreSQL version: 8.2.4 Operating system: Windows Server 2003 Web Edition Description: wrong results at using ltree Details: I think I found a bug in the ltree module. The following query should return false but I get true. SELECT '5.0.1.0'::ltree ~ '5.!0.!0.0'::lquery I get the same result with the 'ltree.dll' of PostgreSQL 8.2.5. If you have a solution of the problem I would be very happy. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
