    we definitely need that error message in other cases, since we have had users bitten hard by that. So some scheme would have to be devised to allow that error to be delayed until table initialization. Would need to also address test/sql/test_columns.py.

    kind of a lame patch. trying to get .type to evaluate later but this gets in the way of trickier pickling scenarios.
