Yes, I consider it a bug in the OGR/PostGIS provider, but I can live 
with it, so I have not reported it.
I probably should though.

Ok, so MapGuide Studio and Maestro encodes the two names differently. 
Thats very very strange.
You can still use Maestro, but its a bit difficult then, because you 
have to manually edit the xml
for the layer, after saving it with Maestro.
In Maestro, modify the layer as desired, then click save, then close.
Now right click the layer on the right, and select "Edit as Xml".
Find the place with the wrong schema, and correct it.
Click save then close.

You may want to view the xml before editing it in Maestro, so you know 
what to change it back to.

Both environments have the preview. In both, it is a button in the 
toolbar above the feature source.
