Couldn't those "multicurves geometries" come from Autocad exports ? I often got files like these where curves are composed of hundreds of vertices and short linestrings. Perhaps are they too many and to close ?

Where are these “shapefiles with curves” you are seeing? the original spec did not include them… any documentation you can point to?

Lately some of the data from local governments contain road data with multicurve geometry. Attempting to load with shp2pgsql fails. 


I've been using ogr2ogr with the -nlt option to specify MULTILINESTRING. 


Is there any better work arounds? According to PostGIS, it does support multicurve geometries. 


Thanks in advance,
