Max Rydahl Andersen commented on HBX-1012:
------------------------------------------

I'm not sure if ignoring all exceptions thrown by a database will be healthy. We do it for some specific scenarioes like index reading since oracle is buggy in this area and it is not vital information for the mappings.

Skipping column reading for complete tables would require more cleaning up and ensuring it won't leave the model broken afterwards - feel free to submit a patch that tries to circumvene it - possibly specifically for informix.
