I would appreciate it if you could file a bug on this issue.

But I think you can workaround the issue by specifying the "-nlt GEOMETRY"
option on the ogr2ogr commandline.

I believe the problem is that the shapefile is identified as type POLYGON
but has some multi-island polygons which translate as MULTIPOLYGON.
Ogr2ogr creates the table with the geometry type polygon, but multipolygon
is not compatible with that and as of PostGIS 1.0 geometry type is
strictly enforced.

The fix is for OGR's Shapefile driver to always return the
layer type as GEOMETRY for polygon files since we can't
know if they are all polygon, all multipolygon or a mix of
the two.
