Hi,<br>
<br>
Thanks for your posting, but that doesnt help me any further.<br>
Maybe its worth a try to downgrade to PostGIS 1.4.<br>
I have no other ideas. Or could someone confirm that the smart Wrapper,
or the give_we_wkt function works with newest postgresql, postgis and
pgouting?<br>
Thanks!<br>
