Can't unparse (to wkt or wkb) polygon with missing end point

[pramsey]

I managed to load this into 1.4 using the 1.3 shp2pgsql utility (so the parser accepted it). And now I can't dump the table because this geometry won't unparse. Fortunately, the GML output is more forgiving:

{{{<gml:MultiPolygon srsName="EPSG:2270">

<gml:polygonMember>

<gml:Polygon>

<gml:outerBoundaryIs>

<gml:LinearRing>

<gml:coordinates>

4280509.572796883992851,250062.898095423181076,1384.223139199977595 4280509.572796883992851,250062.898095423181076,1384.223139199977595

4280509.572796883992851,250062.898095423181076,1384.223139199977595

</gml:coordinates>

</gml:LinearRing>

</gml:outerBoundaryIs>

</gml:Polygon>

</gml:polygonMember>

</gml:MultiPolygon>}}}

It's a three-point polygon where startpoint != endpoint.
