MapServer and PostGIS GEOMETRY type

[Delfos, Jacob]

Hi List,

For a particular client I have to translate a lot of MapInfo files into PostGIS. Some files may contain some different geometries, which ogr2ogr doesn't like. So I force the geometry type to "GEOMETRY" (-nlt GEOMETRY). It translates fine, and seems to draw fine in MapServer. But how does MapServer really deal with it?
If I have a polygon layer, and point it to a PostGIS table that contains objects of the type "GEOMETRY", does it simply ignore anything that is not a polygon? What about the results of attribute queries? Would those be filtered on the geometry type of the layer?

I can avoid using "GEOMETRY type" by translating the files in FME, but I'd prefer to recommend an Open Source solution.

Regards,

Jacob
