[postgis-users] remove duplicate line segments from table

[Murray Richardson]

Hello

I am trying to remove duplicate line segments from a table for segments 
with matching start and end coordinates.  However, I need to include a 
tolerance of about 2m since they are not exact matches.  Also the start 
and end coordinates of matching segmets may be reversed!?  Is there a 
canned way to do this with postGIS?

Thanks for any help.
