Hi all,

first I am knew to RoR, so please excuse if this is a stupid question.

I am fighting to get RoR work with custom postgres database types. I  
am using pg\_shere types like scircle, spoint …

Is there a way to define a mapping from native db types to ruby  
classes I’d like to use?

Thanks

Dominik
