It seems you're right...I took the host parameter out from one of my mapfiles, 
and worked the same as before.

You might want to try adding "using srid=#### using unique oid" to your data 
string (add the appropriate srid for your later, and oid can be replaced with 
any unique column).  Also, do you not need a 'SIZE' parameter in your style for 
the layer?

Did you add your geometry column to your table using the AddGeometryColumn 
function in PostGIS?  I'm not really sure, but Mapserver might be expecting 
information from the geometry_columns table...

Perhaps the mapserver users list would be a good place to check at this point...

Mike.
