Hi,

I tried to import the sample soils map from
PostGIS (1.1.x, on PG 8.0.x):

ogrinfo "PG:host=localhost dbname=postgis" soils | head -25
INFO: Open of `PG:host=localhost dbname=postgis'
using driver `PostgreSQL' successful.

Layer name: soils
Geometry: Polygon
Feature Count: 737
Extent: (589443.750000, 4913923.000000) - (609546.187500, 4928106.000000)
Layer SRS WKT:
PROJCS["UTM Zone 13, Northern Hemisphere",
    GEOGCS["clark66",
        DATUM["North_American_Datum_1927",
            SPHEROID["clark66",6378206.4,294.9786982]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433]],
    PROJECTION["Transverse_Mercator"],
    PARAMETER["latitude_of_origin",0],
    PARAMETER["central_meridian",-105],
    PARAMETER["scale_factor",0.9996],
    PARAMETER["false_easting",500000],
    PARAMETER["false_northing",0],
    UNIT["meter",1]]
FID Column = ogc_fid
Geometry Column = wkb_geometry
cat: Integer (0.0)
label: String (0.0)


But GRASS tells me:
v.in.ogr dsn="PG:host=localhost dbname=postgis" layer=soils  output=soils_pg type=boundary,centroid
ERROR: Projection of dataset does not appear to match current location.

       LOCATION PROJ_INFO is:
       name: UTM
       datum: nad27
       nadgrids: conus
       proj: utm
       ellps: clark66
       a: 6378206.4000000004
       es: 0.0067686580
       f: 294.9786982000
       zone: 13

       cellhd.proj = 0 (unreferenced/unknown)

       You can use the -o flag to v.in.ogr to override this check.
       Consider to generate a new location with 'location' parameter from
       input data set.


It seems that there are still definition issues with PROJ.

any ideas?

 Markus
