[mapguide-users] Re: Item X is already in this named collection

Hello Jackie,

I tried to use the OSgeo. PostGreSQL providers but I get this error message:
An exception occurred in FDO component.
RDBMS: Not connected to the specified database.

I didn't change the feature source before I created the layer, so I don't
think that is the problem for the OSgeo.PostGIS provider.

I would like to use the new provider, but it doesn't work at all for now and
I don't know how to make it work! If you have any other tricks, I will be
more than happy.

Although OSGeo.PostGIS and OSGeo.PostgreSQL are both FDO providers for
PostGIS databases. They are implemented differently and as a result:

 - They require different connection parameters
 - They have different naming conventions for schemas/classes/properties.
What this means is that your PostGIS layers will probably break if you
change your feature source from OSGeo.PostGIS to OSGeo.PostgreSQL or vice
versa.

Also note the general consensus is that OSGeo.PostGIS has been really
unreliable for production use, and if possible you should use the
OSGeo.PostgreSQL provider which is newer and will be getting more attention
from Autodesk.
